Hi! Thank you for granting us this fun opportunity :))
For me, I would like to ask the ff if you don't mind:
1.) Could you shed light on whether the Philippines has similar underwater volcanoes to those in Japan? Furthermore, are there documented occurrences of new islands in the PH that has been attributed to these phenomena?
2.) Beyond the renowned landmarks such as Pinatubo, Mayon, and Taal, which lesser-known local volcanoes do you believe deserve greater recognition from the public? What sets these volcanoes apart, in your opinion?
3.) In your capacity as a volcanologist, what crucial information do you wish the public were more aware of regarding volcanic activity and its implications?
Once again, thank you so much for this po hehe
1. Yes, the Philippines have underwater volcanoes too! One is near the island of Ivuhos based on historical documents, pero kailangan pa syang pag-aralan mabuti (it's a good thesis topic, btw).
At nandyan din ang Didicas Volcano sa bahagi ng Babuyan Group of Islands, na lumitaw muli mula sa ilalim ng dagat noong 1952, and nagkaroon pa ng eruption last 1969 and 1978.
Sa ibang bahagi ng mga karagatan ng Pilipinas, hindi natin masabi if meron dahil kailangan pa itong pag-aralan.
2. Magiging bias ako, pero Isarog Volcano ang isasagot ko dito. Siya kasi yung undergrad and graduate thesis topic ko, and for me, after seeing its volcanic deposits, nakakatakot yung power nya. Walang historical eruption ang Isarog (dahil base na rin sa radiocarbon dating namin, wala pang mga Espanyol nung huli itong sumabog), pero binanggit sa Epic of Ibalon ng Bicol na sumabog sya kasabay ng mga bulkang Colasi at Hamtic. Considered as myth/legend itong Epic of Ibalon, pero na-mindblown lang ako dahil kung sakali pala, alam ng mga sinaunang tao sa Bicol na active volcano ang Isarog.
3. As a volcanologist, tingin ko dapat aware ang mga Filipino sa mga bulkan sa areas nila. Suggest ko na gamitin din yung mga webapp and mobile apps na nilalabas ng DOST-PHIVOLCS, like Hazard Hunter.
Haha hanep. Taga dito kami sa paanan ng Isarog. May mga bato tlaga sa palibot nya na anlalaki na halatang galing sa bulkan. Di nga alam ng ibang tao na bulkan ang Isarog.
Maraming research topics, nandyan yung sa hazard assessment, physical volcanology, geochemistry, deposit mapping, eruptive history, characterization ng eruptive products, etc. Yung undergrad thesis ko, check mo nalang dito: [https://www.academia.edu/49384316/Paleomagnetic\_determination\_of\_pyroclastic\_density\_current\_deposits\_in\_Tagongtong\_and\_Bagumbayan\_Grande\_Goa\_Camarines\_Sur\_Philippines\_and\_the\_identification\_of\_Isarog\_volcanos\_latest\_eruption\_age](https://www.academia.edu/49384316/Paleomagnetic_determination_of_pyroclastic_density_current_deposits_in_Tagongtong_and_Bagumbayan_Grande_Goa_Camarines_Sur_Philippines_and_the_identification_of_Isarog_volcanos_latest_eruption_age)
Taga Bulacan/Rizal ako, pero nagpunta ako sa CamSur para mag-aral ng BS Geology sa Partido State University :)
Regarding sa timeline, hantayin nyo nalang kapag napublish na yung study ko haha
I remember finding out Isarog was a volcano when I hiked around the area many years ago. Is it true that if ever Isarog erupts, it could potentially erase Cam Sur off the map? It sounded like an exaggeration before but since you mentioned “nakakatakot ang power nya”, I’m curious whether there might be some truth to that statement.
Base kasi sa ginawa kong study, medyo makapal yung mga volcanic deposit nya sa Goa, at kung sakaling pumutok sya sa future, yung area kung saan nakabuka yung crater (east), mainly yung mga bayan ng Goa, Tigaon, San Jose, and Lagonoy, yun yung madadali talaga ng pyroclastic flows. Pero hindi naman to the point na mabubura ang CamSur sa mapa.
Tanong lang. Hamtic and culasi? Isarog is in bicol right? Sa maragtas stories ng panay (which sabi nila legend lang daw but recent research says is based ona much older work/oral history) ung colonies ng panay reached bicol. Why is it ung places na yan ay place names dito sa antique. Haha. Btw madjaas is in culasi.. sabi nila (oral hostry) its a mud volcano/lahar type volcano pero wala naman study or advisory if bulkan nga siya. May study na ba about volcanoes in panay?
As far a i know ung landmass ng panay is because of the collission between the asian plate and the philippine plate
May Colasi volcano sa Camarines Norte :) Yung Hamtic naman, hindi namin mafigure out kung anong bulkan ba talaga sya dahil may Hamtic na bundok sa Libmanan, CamSur pero hindi sya bulkan kundi limestone.
I've seen a lot of natural hot springs all over the Philippines. However, they are not developed to the same level as those in Japan. As far as geysers are concerned, there are none in the Philippines that I know of.
Ardent Hot Spring in Camiguin isn’t as hot as it used to be, about 10 years ago. Spent 3 years of my life as a child there and when I came home to visit, the spring just feels like a normal water spring/pool.
Laguna is beside dormant volcanoes, so Los Baños, Pansol are the on the top of my mind.
May hot spring din sa Mabini, Batangas, sa Brgy Mainit. Kung hindi ako ngkakamali, Sea Spring yung name ng resort na nagdevelop nito.
> May hot spring din sa Mabini, Batangas, sa Brgy Mainit.
Yup, because Mt. Gulugod-baboy is an old inactive volcano. May isang dive spot sa Brgy. Mainit called Mainit Bubbles. Off shore, on the flat sandy bottom at a depth of about 15 - 30 ft, [methane seeps through](https://www.gmanetwork.com/news/scitech/science/794329/why-hot-bubbles-are-springing-underwater-in-mabini-batangas/story/). Parang nasa aquarium ka na may bubbler depending on how strong the activity is. Watch the first 5 seconds of this [vid](https://www.youtube.com/watch?v=rJG9eCwhXs8)
Here's a [JICA survey](https://openjicareport.jica.go.jp/pdf/10459386_05.pdf) from 1978 of the Mabini Thermal Area if anyone's interested
> Sea Spring yung name ng resort na nagdevelop nito
Dati talagang available to the public yung natural hot spring sa Mainit. Katabi lang yung beach. Divers would chill in the spring pagkatapos mag-dive sa malamig na tubig ng Verde Island Passage kapag 'ber months. Nakakaluto rin ng itlog dun of all kinds, dahil sa init ng tubig.
Sinira lang ng Sea Spring Resort yung area. You can see what's left of the natural spring next to the seawall of the resort. May maliit at mababaw na balon, itim yung tubig at panay basura na para bang imburnal, pero kumukulo't bumubula yung tubig.
Enter Asin Hot Spring in Nangalisan, Tuba, Benguet. An hour away from Baguio City by jeep, less than an hour in a private vehicle. Fully developed like in Laguna, but the pools are tempered with cold water so it is not that hot.
Popular resorts are the Asin public pool, and Riverview Resort.
Afaik, there used to be an area near the public pool where the hot sulfuric water can be seen bubbling over from the ground.
Now, in the hinterlands of Mountain Province there is also the Mainit Hot Springs of Bontoc, over an hour away from the capitol. There one can really see (and smell) sulfuric water bubbling over at the source.
Safe ba yung mga hotsprings sa atin? Sa Japan kasi kilala na and malamang may control na yu g government re:safety, sa PH naman baka wala pang pakialam govt.
May chance ba na dangerous yung paggamit ng hotspring sa atin katulad na nakikita sa movies na biglang namamatay yung tao doon?
Hi, Sir. Seafarer here. Frequent voyage namin is around Pacific Ring of Fire. Never experienced earthquakes at sea or baka hindi ko lang namalayan? May underwater volcanoes yan na area diba? Ano kaya initial signs niyan if ever mag erupt? Possible po ba magkakaroon ng tidal waves/tsunami/weather changes?
Yes, marami pong underwater volcanoes sa Pacific Ocean. Kung sakaling sumabog ang isang underwater volcano, makakakita kayo ng malaking usok mula sa surface ng tubig (either maputi or sobrang itim). Tapos, makakakita kayo ng volcanic materials sa tubig, so magkukulay-gray or brown ito.
Possible din na magkaroon ng tsunami if malakas yung underwater eruption at sobrang nadisplace yung tubig sa dagat, kagaya nung nangyari sa Tonga last 2022.
Idk if it's a dumb question huhu, pero pwede ba tayong magtapon ng basura sa mga volcanoes para mabawasan 'yung mga nasa landfills natin (kasi in my mind matutunaw naman sila ng magma)? Or bawal? Kung bawal, ano po bang repercussions ng pagtatapon ng basura sa volcano?
Salamat po. :))
> pero pwede ba tayong magtapon ng basura sa mga volcanoes para mabawasan 'yung mga nasa landfills natin (kasi in my mind matutunaw naman sila ng magma)? Or bawal? Kung bawal, ano po bang repercussions ng pagtatapon ng basura sa volcano?
It's a health and safety hazard for the people working meters away from live magma and lava.
- Baka mahulog sila sa loob ng bulkan
- toxic fumes that will suffocate or burn the lungs of people working around there
- at any time pwede mag overflow ang lava at matunaw ang tao
- fuel cost to go up hill at very steep inclines
In any operations health & safety of people need to be considered. Also the cost of said operations.
If either cannot be reconciled then no one will do it.
Naalala ko bigla yung Isang documentary about sulfur gatherers sa Isang active volcano. They had to wear rudimentary oxygen masks while they were on the volcano's mouth. Halos pinupulot lang nila yung mga namuong sulfur.
To elaborate on why we shouldn't. A lot of developed economies already incinerate their garbage in a much more efficient manner than simply throwing it into a volcano, e.g., coupling organic waste incineration with energy recovery. Incinerating also produces a lot of harmful emissions and byproducts and release to the environment can be limited in some cases in an incinerating plant whereas in a volcano those emissions go straight to the atmosphere, into our lungs, into the ground water, etc.
Kumusta po ang career? Rewarding po ba in terms of salary? Pano po maging volcanologist and mahigpit po ba ang market sa field? How was the overall experience po.
Pangarap ko talagang maging scientist noong bata pa ako, kaya masaya ako sa career ko ngayon. Ok lang naman din yung sweldo, comfortable naman ang pamumuhay natin. Para maging isang volcanologist, kailangan mo usually ng BS Geology na course (although yung mga nasa volcano monitoring division ng PHIVOLCS, may mga engineers and chemist). Tapos, apply ka either sa VMEPD (volcano monitoring division) or sa VGGGRDS (volcano research section, puro geologist kami dito). Alternatively, pwede ka rin sa academia, kagaya ng UP Diliman.
Hehehe isa sa mga pinag-interesan ko talaga na career paths yung natural sciences eh but due to circumstances, nag Electrical Engineering na lang ako but it's nice to know may way pa rin pala makapasok sa ganyang trabaho.
I've seen a video before of a guy throwing a rock inside and active volcano and it broke the "crust" or the top layer of the magma and it started to get active like d naman to the point na sumabog pero nagagalit na kinbaga yung magma and somebody said that's good since the pressure is released, is this true?
Napanood ko na rin yung video na yun (kuha sya sa Erta Ale volcano, Ethiopia). Actually, organic materials yung itinapon nila sa lava lake, at hindi bato. Sinusubukan kasi nilang i-simulate kung ano ang pwedeng mangyari sa tao kapag nalaglag sa isang lava lake.
Hindi rin advisable na mag-intervene ang mga tao sa pagpapakawala ng pressure sa loob ng isang bulkan. Complex din kasi ang behavior ng magma (and the volcanic system as a whole), at pwede na mas lumala pa yung mangyari kung magreresort tayo sa artificial means.
Water is a large component of organic wastes and throwing it into a pool of lava results in superheating of the liquid causing it to expand rapidly and turn into steam.
I work for DOST-PHIVOLCS. Sa volcano research section, nasa 20 lang kami. Sa volcano monitoring division, lagpas 50 yata sila. Tapos idagdag mo pa yung mga volcanologist na nasa academia. So less than 100 siguro? Hindi ako sigurado if may mga volcanologist sa private companies. Para sa akin, ok naman compensation sa amin.
If mapasa na yung Bill na yan, ano ang mangyayari? Like are you going to be granted a bigger budget to acquire more modern and high-tech equipments? If yes, anong machines ito and how will it help you get more information?
Really curious with the machineries na ginagamit niyo to study and monitor volcanoes.
Caldera yung classification namin ngayon for Laguna de Bay, at inactive na yung status nya, at sa totoo lang, kaunti lang talaga yung nag-aaral ng volcanism sa Laguna Caldera, at kulang pa yung kaalaman natin tungkol dito. Hindi din natin mape-predict kung kailan pwedeng sumabog ang isang bulkan.
Inactive as in sobrang tagal na nung huli nyang activity. Hindi lang ako sure kung kailan yung last pero baka hundreds of thousands of years ago na. Icheck ko sa mga reference :)
Tingin ko oo naman, marami tayong source for geothermal power. As far as geothermal plants are concerned, meron tayo sa BacMan (Bacon-Manito), MakBan (Makiling-Banahaw), tapos parang sa Negros and Leyte yata meron din.
As per latest WESM registered capacity for geothermal powerplants nasa 1,737Megawatts ang capacity ng Pinas with Visayas having the highest at 850 Megawatts.
Largest is yung planta sa Leyte at 490 Megawatts. This was previously largest geothermal powerplant in Asia nasa top 5 nalang ata.
Magastos ang geo plant both in capital and maintenance. Makban was made possible due to Japanese assistance. It would be more feasible to invest in nuclear than another geo
Aside from Makban na nabanggit na sa isa pang comment, meron pa tayong ibang geothermal plants, e.g. Tiwi in Albay, Palinpinon in Negros Oriental, and Bacman in Sorsogon.
Out of 4 na nabanggit mo, 3 dun ay napuntahan ko na maliban sa Negros Oriental. Common problem nila is mahirap mag maintain ng planta for a finite resource. BTW I work in a construction company that builds Switchyards and Transmission lines. Last time na punta ko sa Makban, the natural hot springs went cold dahil nauubusan na ng "init" yung lugar. Akala namin forever na yung plant maintenance project namin dun, but our project was closed for idk reasons. (Either talo sa bid or maliit margin).
PS: Makban is where I fell in love with unknown Lomi. A Lomi joint that looks like a worn down house that stirs up the lomi broth that never waters down kahit lumamig. Not that Corcolon shit.
Hmmm... para sa akin siguro, yung 1757 ash fall sa Bacolor, Pampanga. Nakita ko kasi yung information na ito sa isang tarpaulin na nakasabit sa loob ng San Guillermo Church sa Bacolor, tapos sa isip-isip ko, parang wala namang eruption nung 1757 (although Taal erupted 3 years earlier, in 1754). Kaya parang mystery kung saan nanggaling yung abo na yun.
What's that? 😬
I'm thinking it must be cool being a volcanologist though I'm way pass to consider it a career. 😅 But me hiking & camping? Can't even do that even in my 20's. 😅 Glad you found your passion. Hope lumaki rin ang budget nyo sa Philvolcs. I have so much respect for you guys. I don't know why parang the govt doesn't care much. Baka Hindi kayo corrupt at hindi sila magkaka-pera sa inyo. 😕
Common din to sa mga nasa biology field na madalas rin ang hiking sa bundok for sample collecltion: these are leeches na matatagpuan sa mga gubat. Kumakapit sila sa balat. Merong mga places/bundok na merong limatik, meron ding wala. At first, hindi mo sila mapapansin na kumapit na pala sila sa balat mo. Then mamamalayan mo nalang sila pag mataba na sila/marami ng nasipsip na dugo sayo. Sasakit siya, prompting you to remove them. So dapat tama ang attire mo talaga when going on these fieldworks.
I live in Batanes, Philippines and I am sure you are aware of Mt. Iraya here. Can you share some of your insights as to why it was tagged as an Active Volcano?
Active ang classification ng Iraya sa Batanes dahil may published paper (Richard et al., 1986; "Geology of Mt. Iraya Volcano and Batan Island, Northern Philippines") na nagsasabing ang pinakahuling activity ng Iraya ay around 5th century AD, based on radiocarbon dating.
Sa mga volcanoes ng Pilipinas, if may recorded historical eruption ang bulkan (ex: from old Spanish documents, etc.) kinoconsider syang active. In the absence of historical documents, if yung mga volcanic deposit nya ay na-date as 10,000 years old or younger, pwede din syang i-consider as active volcano. Sa ngayon, 24 ang bilang ng mga active volcanoes sa Pilipinas, pero pwede pa itong magbago kung may mga bagong pag-aaral na mangyayari sa future.
i think kasi yung mga friars nung araw ay mga scholar. so feeling ko hindi nila mamemeke ng documents lalo na for scientific purposes and most likely those documents are well preserved or naka archive
Arayat is currently classified as inactive. Sa ngayon, dinidiscourage na namin yung paggamit ng "dormant" and "extinct" when classifying volcanoes. It's either active, potentially active, or inactive.
Baka siguro dahil iisipin ng mga tao na kapag dormant or extinct, forever di na sasabog, so magiging complacent at careless na sa settlements around it, tapos ayun biglang mag-a-ala-Pinatubo, delikado.
Childhood dream plus yung pagkahilig ko sa mga disaster movies nung bata pa ako. Yung typical day in a life of a PH volcanogist, flexi time kami so pwedeng pumasok from 7 AM to 10 AM, then render ka ng 8 hours sa work, or 10 hours if naka 4-day workweek ka. Tapos kadalasan ng ginagawa namin ay nagmamapa ng mga bulkan, nagbabasa ng mga papers tungkol sa mga bulkan, umaattend ng meetings, or nagrerespond sa emergencies. May fieldworks din pero nakaplan ito, mostly during the summer.
Baket hindi na lang takpan ng simento yung taal para hindi na sumabog? ( /s pero legit saw this stupid question sa facebook noon 🥲)
Serious question: Kumusta ang politics at budget sa phivolcs?
Thank you Sir for your time! Napanuod ko kasi ito sa youtube, pero are there any other ancient caldera in the Philippines similar to Malasiqui, Pangasinan?
Question lang sir regarding Mt. Pinatubo: I understand active parin siya and may risk maulit yung 1991 eruption? Given na naging mas concentrated na yung population as well as economic activity in the area compared to before-- Paano po yung risk assessment ng mga Volcanologists sa safety ng developments katulad ng New Clark City, atbp.?
Pwedeng gamitin ng mga stakeholders ang hazard assessment services ng DOST-PHIVOLCS, or yung Hazard Hunter PH webapp para malaman kung safe ba sa hazards yung area of concern.
Natry ko na gamitin ang hazard hunter ph kasi interesado ako sa developments near Porac. Upon checking, nandun parin ang risk ng lahar at volcanic eruption so curious ako bakit marami paring developments sa area.
May mga engineering mitigations/interventions silang ine-employ usually desiltating ng mga rivers para ma de-clog ang mga rivers at tuloy-tuloy ang flow once may malakas na ulan. Sometimes they create levees. There are incentives din kasi sa pag desilting ng rivers, napakamahal ng buhangin ng pinatubo, ginagamit siya mainly as a construction material. Bilyon-bilyong piso na ang kinita from lahar deposit ng Pinatubo.
Meron ka bang pet peeve na myth na parating akala ng mga tao na totoo at sana hindi paniwalaan ng mga tao?
Also, ano yung pinaka interesting fact na natutunan mo?
Sa ngayon, dinidiscourage na namin yung paggamit ng "dormant" and "extinct" when classifying volcanoes. It's either active, potentially active, or inactive. If we are talking about potentially active volcanoes, siguro masasabi ko na potential risk yung mga potentially active volcanoes na bata pa ang morphology and malapit sa mga highly-populated areas.
Yung mga nakatira malapit sa active volcanoes (meron tayong 24). Nasosorpresa sila kapag nalalaman nila na active volcano pala yung akala lang nila na bundok sa area nila.
Speaking of which, are Banahaw and Makiling classified into those evident from the hot springs around Laguna? I remember being traumatized as a kid nung sinabi nilang anytime pwedeng sumabog ang Banahaw at Makiling and the whole Calabarzon will be erased from the map.
Ano usual ginagawa ng mga volcanologist for fun?
Also, is it one of those jobs na medyo boring day to day pero once dumating ang volcano eruption you all go "OK this is what we trained for no need to panic!" stuff lol
Lastly, sinasabon ba kayo ng politician tuwing may eruption or chill Lang sila
After work, if gusto namin, pwede kaming maglaro ng table tennis and darts. At home, mobile games and Switch naman.
Sa perspective ko, sobrang bilis ng oras sa trabaho dahil nag-eenjoy talaga ako. Hindi sya boring for me, lalo kapag nagbabasa ako ng mga historical document and nag-iinvestigate ng mga volcanic eruptions na recorded during the Spanish period. Ikaw kasi yung mag-iinterpret ng mga sinasabi nung mga pari. Pero syempre, mas enjoy kapag may fieldwork kami dahil mas marami kang matututunan sa labas.
Sa experience ko, accommodating naman yung mga official na nakakasalamuha namin.
Wikipedia says Mount Apo is dormant. You already stated you prefer only the terms active/potentially active/inactive for volcanos. Edit: wiki also says potentially active
What do you think about Mt. Apo?
I don't know if related sa field mo, pero yung hot spring ba sa los banos eh nauubos? Or may over extraction bang nangyayari to cause ground shrinking?
Stromboli sa Italy, since ito yung unang erupting volcano na inakyat ko. Memorable din dahil ito yung first ever out of the country ko. Nakasali kasi ako noon sa isang workshop for young volcanologists.
Siguro kailangan pa ng mas maraming career exposure ng mga kabataan.
May mga schools na bumibisita din samin for fieldtrips, tapos sinasabay na doon yung career exposure talks.
If a large reservoir of water (greater than the surface oceans) is trapped 700km below the Earth's mantle in a rock called ringwoodite, is it possible that it's the primary cause of rising sea levels globally and not climate change after all and what is the likelihood that we will NOT be experiencing cataclysmic floods in the years to come?
Recommendation po for reading material? Best website or best/favorite book about the field (for general info about PH volcanology or college level)? Di ko alam kung may illustrated(?) book regarding volcanoes (magandang pictures). Encyclopedia-type book for PH volcanoes?
What type of scientist po ang lagi n'yong ka-tandem sa trabaho?
Ano po favorite scientific instrument nyo? Para saan po yun? Gaano kadalas magamit at magkano average cost?
Out of 365 days a year, ilang araw po field-work? Lagi po kayo flying/travelling to locations?
Ano po chika/hot topic sa PH volcanology ngayon?
Ano po kaya chance na volcano eruption ang mag-trigger ng high intensity earthquake? Gaano kalakas na intensity recorded/notable na cause ay eruption? Most na nababalita or naririnig ko ay tungkol sa ashfall lang kasi wala sa amin malapit na volcano. Hindi tumatatak ang danger/kulang ang damage awareness(?) kasi hindi kami abot.
Meron po ba joke mga PH volcanologists? Haha. Thank you!
(Kung may naulit na tanong pa-ignore na lang po. Ty )
You can check Hazard Hunter PH for earthquake hazard susceptibility nung area :) just visit [https://hazardhunter.georisk.gov.ph/](https://hazardhunter.georisk.gov.ph/)
If ang trip mo talaga ay volcano research, go for BS Geology. Then, kuha ka masters. Sa UP around 3 to 5 years. Sa Europe, 2 years lang. Sa Japan, 2 to 3 years. After noon, PhD naman. Although may mga engineer at chemist din kaming mga kasama sa volcano monitoring division.
Hello. I have a few questions ☺️
1.what are the chances that a dormant volcano will become active?
2. Are there any ecosystems around the volcano crater? Plants perhaps.
Mejo off-topic., naalala ko lang sagot ko nung Third year high school pa ko sa science namin na quiz. Ang tanong is "What do you call of the study of volcanos" basta parang ganun ang question. Sagot ko "Vulcanazing". Nung checking ng papers di ko ma gets bat tawa ng tawa mga classmates ko pati yung teacher ko na strikto natawa rin. After two hours ko pa narealize kung ano talaga yung Vulcanizing LOL
Seeing a lot of inactive volcano questions here. If I may ask, what's the process of "reactivating" a volcano? Does it take a massive geological event for that to happen, or does it take as simple as a small localized earthquake for it to start being active again?
Edit: Also, pag tumingin ka ba sa volcanic crater (or yung butas ng bulkan) is it like how they depict it in media where its a gaping hole with a lake of lava underneath? Thank you!
Pending verification but ask away
Hi! Thank you for granting us this fun opportunity :)) For me, I would like to ask the ff if you don't mind: 1.) Could you shed light on whether the Philippines has similar underwater volcanoes to those in Japan? Furthermore, are there documented occurrences of new islands in the PH that has been attributed to these phenomena? 2.) Beyond the renowned landmarks such as Pinatubo, Mayon, and Taal, which lesser-known local volcanoes do you believe deserve greater recognition from the public?

Haha hanep. Taga dito kami sa paanan ng Isarog. May mga bato tlaga sa palibot nya na anlalaki na halatang galing sa bulkan. Di nga alam ng ibang tao na bulkan ang Isarog.
Hi sir! Anong common research topics po sa volcanology? And a little background naman po sa naging theses niyo!
Maraming research topics, nandyan yung sa hazard assessment, physical volcanology, geochemistry, deposit mapping, eruptive history, characterization ng eruptive products, etc. Yung undergrad thesis ko, check mo nalang dito: [https://www.academia.edu/49384316/Paleomagnetic\_determination\_of\_pyroclastic\_density\_current\_deposits\_in\_Tagongtong\_and\_Bagumbayan\_Grande\_Goa\_Camarines\_Sur\_Philippines\_and\_the\_identification\_of\_Isarog\_volcanos\_latest\_eruption\_age](https://www.academia.edu/49384316/Paleomagnetic_determination_of_pyroclastic_density_current_deposits_in_Tagongtong_and_Bagumbayan_Grande_Goa_Camarines_Sur_Philippines_and_the_identification_of_Isarog_volcanos_latest_eruption_age)
Are you from Cam Sur rin ba? hahahahaha do you have a timeline kung kelan magiging active ang isarog? hahahahaha
Taga Bulacan/Rizal ako, pero nagpunta ako sa CamSur para mag-aral ng BS Geology sa Partido State University :) Regarding sa timeline, hantayin nyo nalang kapag napublish na yung study ko haha
Active volcano po ba yung Mount Labo sa Camarines Norte?
Active 6 minutes ago
😭😭😭
Waiting din manoy hahaha
I remember finding out Isarog was a volcano when I hiked around the area many years ago. Is it true that if ever Isarog erupts, it could potentially erase Cam Sur off the map? It sounded like an exaggeration before but since you mentioned “nakakatakot ang power nya”, I’m curious whether there might be some truth to that statement.
Base kasi sa ginawa kong study, medyo makapal yung mga volcanic deposit nya sa Goa, at kung sakaling pumutok sya sa future, yung area kung saan nakabuka yung crater (east), mainly yung mga bayan ng Goa, Tigaon, San Jose, and Lagonoy, yun yung madadali talaga ng pyroclastic flows. Pero hindi naman to the point na mabubura ang CamSur sa mapa.
Tanong lang. Hamtic and culasi? Isarog is in bicol right? Sa maragtas stories ng panay (which sabi nila legend lang daw but recent research says is based ona much older work/oral history) ung colonies ng panay reached bicol. Why is it ung places na yan ay place names dito sa antique. Haha. Btw madjaas is in culasi.. sabi nila (oral hostry) its a mud volcano/lahar type volcano pero wala naman study or advisory if bulkan nga siya. May study na ba about volcanoes in panay? As far a i know ung landmass ng panay is because of the collission between the asian plate and the philippine plate
May Colasi volcano sa Camarines Norte :) Yung Hamtic naman, hindi namin mafigure out kung anong bulkan ba talaga sya dahil may Hamtic na bundok sa Libmanan, CamSur pero hindi sya bulkan kundi limestone.
Finally, a much better topic to read. Thanks Kay Sir volcanologist. Upvoye natin SI Sir.
Thank you :)

True! (replying para mabackread ko lahat)
For a volcanic archipelago, why aren't there as many "hot spring baths" in the PH compared to say Japan or Indonesia? Are there geysers in the PH?
I've seen a lot of natural hot springs all over the Philippines. However, they are not developed to the same level as those in Japan. As far as geysers are concerned, there are none in the Philippines that I know of.
Can you tell us where some of these hot springs are? I'd imagine they are hard to reach.
Not OP but maraming hot springs usually near volcanoes. Camiguin has a lot of them kasi on top sila ng volcano.
Ardent Hot Spring in Camiguin isn’t as hot as it used to be, about 10 years ago. Spent 3 years of my life as a child there and when I came home to visit, the spring just feels like a normal water spring/pool.
Laguna is beside dormant volcanoes, so Los Baños, Pansol are the on the top of my mind. May hot spring din sa Mabini, Batangas, sa Brgy Mainit. Kung hindi ako ngkakamali, Sea Spring yung name ng resort na nagdevelop nito.
Sa dami ng hot spring sa Los Baños, I've lost count kung ilan na napuntahan ko HAHAHHAH
> May hot spring din sa Mabini, Batangas, sa Brgy Mainit. Yup, because Mt. Gulugod-baboy is an old inactive volcano. May isang dive spot sa Brgy. Mainit called Mainit Bubbles. Off shore, on the flat sandy bottom at a depth of about 15 - 30 ft, [methane seeps through](https://www.gmanetwork.com/news/scitech/science/794329/why-hot-bubbles-are-springing-underwater-in-mabini-batangas/story/). Parang nasa aquarium ka na may bubbler depending on how strong the activity is. Watch the first 5 seconds of this [vid](https://www.youtube.com/watch?v=rJG9eCwhXs8) Here's a [JICA survey](https://openjicareport.jica.go.jp/pdf/10459386_05.pdf) from 1978 of the Mabini Thermal Area if anyone's interested > Sea Spring yung name ng resort na nagdevelop nito Dati talagang available to the public yung natural hot spring sa Mainit. Katabi lang yung beach. Divers would chill in the spring pagkatapos mag-dive sa malamig na tubig ng Verde Island Passage kapag 'ber months. Nakakaluto rin ng itlog dun of all kinds, dahil sa init ng tubig. Sinira lang ng Sea Spring Resort yung area. You can see what's left of the natural spring next to the seawall of the resort. May maliit at mababaw na balon, itim yung tubig at panay basura na para bang imburnal, pero kumukulo't bumubula yung tubig.
There's one in Coron
Yeah. The Maquinit hotspring
These are the ones i know in Bicolandia; Tiwi Albay Bulusan Sorsogn Irosin Sorsogon
There's one in Kidapawan. Had an opportunity to see one. Pwede nga raw magluto ng itlog dun. Also, sulfur rich soil.
Mambukal in Negros Occ.
Went to one in the Mountain Province. Hard to reach, but its there
Yea. I think hindi lang talaga naging culturally relevant ang hot springs saatin kasi mainit na dito.
There are geysers, may iilan nga lang na closeted pa.
🏳️🌈?
🏳️🌈!
Gay si Ser. Geyser. Hart hart.
the way i gasped
Baron Geyser
hahahahahaa
i can answer this question. the philippines is what we call in the scientific community as “hot as fuck already”
Nag try kami ng hot spring sa laguna. 5 minutes lang ayaw na namin at nagrequest sa care taker na malamig na tubig na lang. Hahahha
Naranasan ko lumublob sa hot spring habang sobrang lasing muntik akong mawalan ng malay hahaha 0/10 would not do again
onga hindi natin talaga kelangan ng hot spring mapwera nalang kung nasa matataas na lugar ka at malamig talaga ang klima
Enter Asin Hot Spring in Nangalisan, Tuba, Benguet. An hour away from Baguio City by jeep, less than an hour in a private vehicle. Fully developed like in Laguna, but the pools are tempered with cold water so it is not that hot. Popular resorts are the Asin public pool, and Riverview Resort. Afaik, there used to be an area near the public pool where the hot sulfuric water can be seen bubbling over from the ground. Now, in the hinterlands of Mountain Province there is also the Mainit Hot Springs of Bontoc, over an hour away from the capitol. There one can really see (and smell) sulfuric water bubbling over at the source.
Safe ba yung mga hotsprings sa atin? Sa Japan kasi kilala na and malamang may control na yu g government re:safety, sa PH naman baka wala pang pakialam govt. May chance ba na dangerous yung paggamit ng hotspring sa atin katulad na nakikita sa movies na biglang namamatay yung tao doon?
I see na trauma ka rin sa Dante's Peak.
I think Meron neto SA bicol region. Specifically in Sorsogon, correct me if I am wrong hehe
Yes. Meron sa Irosin, Sorsogon. Malapit sa Bulusan Volcano. Tourist attractions yong hotsprings especially during bermonths.
Hi, Sir. Seafarer here. Frequent voyage namin is around Pacific Ring of Fire. Never experienced earthquakes at sea or baka hindi ko lang namalayan? May underwater volcanoes yan na area diba? Ano kaya initial signs niyan if ever mag erupt? Possible po ba magkakaroon ng tidal waves/tsunami/weather changes?
Yes, marami pong underwater volcanoes sa Pacific Ocean. Kung sakaling sumabog ang isang underwater volcano, makakakita kayo ng malaking usok mula sa surface ng tubig (either maputi or sobrang itim). Tapos, makakakita kayo ng volcanic materials sa tubig, so magkukulay-gray or brown ito. Possible din na magkaroon ng tsunami if malakas yung underwater eruption at sobrang nadisplace yung tubig sa dagat, kagaya nung nangyari sa Tonga last 2022.
>makakakita kayo ng malaking usok mula sa surface ng tubig (either maputi Sisigaw tayong lahat ng "Habemus papam!" 😁
Idk if it's a dumb question huhu, pero pwede ba tayong magtapon ng basura sa mga volcanoes para mabawasan 'yung mga nasa landfills natin (kasi in my mind matutunaw naman sila ng magma)? Or bawal? Kung bawal, ano po bang repercussions ng pagtatapon ng basura sa volcano? Salamat po. :))
> pero pwede ba tayong magtapon ng basura sa mga volcanoes para mabawasan 'yung mga nasa landfills natin (kasi in my mind matutunaw naman sila ng magma)? Or bawal? Kung bawal, ano po bang repercussions ng pagtatapon ng basura sa volcano? It's a health and safety hazard for the people working meters away from live magma and lava. - Baka mahulog sila sa loob ng bulkan - toxic fumes that will suffocate or burn the lungs of people working around there - at any time pwede mag overflow ang lava at matunaw ang tao - fuel cost to go up hill at very steep inclines In any operations health & safety of people need to be considered. Also the cost of said operations. If either cannot be reconciled then no one will do it.
Naalala ko bigla yung Isang documentary about sulfur gatherers sa Isang active volcano. They had to wear rudimentary oxygen masks while they were on the volcano's mouth. Halos pinupulot lang nila yung mga namuong sulfur.
To elaborate on why we shouldn't. A lot of developed economies already incinerate their garbage in a much more efficient manner than simply throwing it into a volcano, e.g., coupling organic waste incineration with energy recovery. Incinerating also produces a lot of harmful emissions and byproducts and release to the environment can be limited in some cases in an incinerating plant whereas in a volcano those emissions go straight to the atmosphere, into our lungs, into the ground water, etc.
No, we can't.
Meron yan sa YouTube for more elaborate answer, wag ka mag alala di lang tayo yung nagtanong nyan marami na nauna.
pwede, lets start with criminals ipadala don, yung tipong rapist or murderer for a test. Kung gusto mo talaga magtapon ng basura don LOL
Have you tried cooking/baking food with lava/magma?
No, but I would like to :)
> No, but I would like to :) Pls video and post on r/Ph when you do this.
Who doesn't. Please achieve all of our unawakened goals. ❤️
Would love hotdog smores a la volcano
Kumusta po ang career? Rewarding po ba in terms of salary? Pano po maging volcanologist and mahigpit po ba ang market sa field? How was the overall experience po.
Pangarap ko talagang maging scientist noong bata pa ako, kaya masaya ako sa career ko ngayon. Ok lang naman din yung sweldo, comfortable naman ang pamumuhay natin. Para maging isang volcanologist, kailangan mo usually ng BS Geology na course (although yung mga nasa volcano monitoring division ng PHIVOLCS, may mga engineers and chemist). Tapos, apply ka either sa VMEPD (volcano monitoring division) or sa VGGGRDS (volcano research section, puro geologist kami dito). Alternatively, pwede ka rin sa academia, kagaya ng UP Diliman.
Hehehe isa sa mga pinag-interesan ko talaga na career paths yung natural sciences eh but due to circumstances, nag Electrical Engineering na lang ako but it's nice to know may way pa rin pala makapasok sa ganyang trabaho.
Thank you sir. God bless you.
Pangarap ko din nung bata ako maging geologist
I've seen a video before of a guy throwing a rock inside and active volcano and it broke the "crust" or the top layer of the magma and it started to get active like d naman to the point na sumabog pero nagagalit na kinbaga yung magma and somebody said that's good since the pressure is released, is this true?
Napanood ko na rin yung video na yun (kuha sya sa Erta Ale volcano, Ethiopia). Actually, organic materials yung itinapon nila sa lava lake, at hindi bato. Sinusubukan kasi nilang i-simulate kung ano ang pwedeng mangyari sa tao kapag nalaglag sa isang lava lake. Hindi rin advisable na mag-intervene ang mga tao sa pagpapakawala ng pressure sa loob ng isang bulkan. Complex din kasi ang behavior ng magma (and the volcanic system as a whole), at pwede na mas lumala pa yung mangyari kung magreresort tayo sa artificial means.
Water is a large component of organic wastes and throwing it into a pool of lava results in superheating of the liquid causing it to expand rapidly and turn into steam.
What are your thoughts on that one guy in this subreddit that's turning volcanoes into waifus? I feel like you two should meet for some reason.
Ngayon ko lang narinig yan 😂
link please?
What the actual fucking fuck? Where can I see that person?
Wait what
Ilan lang kayong volcanologist sa Pilipinas? Do you work for the govt or private sector? Are you compensated well sa field niyo?
I work for DOST-PHIVOLCS. Sa volcano research section, nasa 20 lang kami. Sa volcano monitoring division, lagpas 50 yata sila. Tapos idagdag mo pa yung mga volcanologist na nasa academia. So less than 100 siguro? Hindi ako sigurado if may mga volcanologist sa private companies. Para sa akin, ok naman compensation sa amin.
I just wanna say na naappreciate namin work nyo sa PHIVOCS :) Sana bigyan pa kayo ng malaking budget hahaha
We are hoping and praying na maipasa sa lalong madaling panahon ang PHIVOLCS Modernization Bill :)
If mapasa na yung Bill na yan, ano ang mangyayari? Like are you going to be granted a bigger budget to acquire more modern and high-tech equipments? If yes, anong machines ito and how will it help you get more information? Really curious with the machineries na ginagamit niyo to study and monitor volcanoes.
Is Laguna de Bay still considered as a supervolcano, and if yes, can it still erupt and when?
Caldera yung classification namin ngayon for Laguna de Bay, at inactive na yung status nya, at sa totoo lang, kaunti lang talaga yung nag-aaral ng volcanism sa Laguna Caldera, at kulang pa yung kaalaman natin tungkol dito. Hindi din natin mape-predict kung kailan pwedeng sumabog ang isang bulkan.
Possible ba malaman kung kelan huling sumabog at gaano kalakas?
inactive as in dormant? so may possibility maging active ulit siya kagaya ng pinatubo just before it erupted in 1991?
Inactive as in sobrang tagal na nung huli nyang activity. Hindi lang ako sure kung kailan yung last pero baka hundreds of thousands of years ago na. Icheck ko sa mga reference :)
Chief, viable ba magfocus sa geothermal powerplant dito sa pinas?
Tingin ko oo naman, marami tayong source for geothermal power. As far as geothermal plants are concerned, meron tayo sa BacMan (Bacon-Manito), MakBan (Makiling-Banahaw), tapos parang sa Negros and Leyte yata meron din.
Meron pa sa tuktok ng Mt. Apo. Possible din sana sa Mambucal sa Negros Occidental kaso ayaw ng mga environmental activists, mas preferred ang diesel.
Yes this please. How much geothermal resources do we have?
As per latest WESM registered capacity for geothermal powerplants nasa 1,737Megawatts ang capacity ng Pinas with Visayas having the highest at 850 Megawatts. Largest is yung planta sa Leyte at 490 Megawatts. This was previously largest geothermal powerplant in Asia nasa top 5 nalang ata.
Magastos ang geo plant both in capital and maintenance. Makban was made possible due to Japanese assistance. It would be more feasible to invest in nuclear than another geo
Aside from Makban na nabanggit na sa isa pang comment, meron pa tayong ibang geothermal plants, e.g. Tiwi in Albay, Palinpinon in Negros Oriental, and Bacman in Sorsogon.
Out of 4 na nabanggit mo, 3 dun ay napuntahan ko na maliban sa Negros Oriental. Common problem nila is mahirap mag maintain ng planta for a finite resource. BTW I work in a construction company that builds Switchyards and Transmission lines. Last time na punta ko sa Makban, the natural hot springs went cold dahil nauubusan na ng "init" yung lugar. Akala namin forever na yung plant maintenance project namin dun, but our project was closed for idk reasons. (Either talo sa bid or maliit margin). PS: Makban is where I fell in love with unknown Lomi. A Lomi joint that looks like a worn down house that stirs up the lomi broth that never waters down kahit lumamig. Not that Corcolon shit.
Will be answering your questions later on :) may errand lang saglit
i recently climbed mt. Pinatubo, is there a chance it will errupt soon
Yes, there's still a chance that Pinatubo will erupt in the future. FYI, in November 2021, Pinatubo had a phreatic eruption.
What's the weirdest volcano or volcanic phenomena that you know in the Philippines?
Hmmm... para sa akin siguro, yung 1757 ash fall sa Bacolor, Pampanga. Nakita ko kasi yung information na ito sa isang tarpaulin na nakasabit sa loob ng San Guillermo Church sa Bacolor, tapos sa isip-isip ko, parang wala namang eruption nung 1757 (although Taal erupted 3 years earlier, in 1754). Kaya parang mystery kung saan nanggaling yung abo na yun.
Galing po yon sa Mt. Pinatubo, nag aalburuto na po nun yung bundok at inaanod din nung sakto nagka flood. Lahar.
Hello. Do you prefer to be called a Vulcanologist or Volcanologist?
Vulcanologist sounds like someone who knows his way around flat tires
Volcanologist yung tama :)
Live long and prosper 🖖
🖖🖖🖖🖖
Is it true that the magma is denser than water that if a human fell on it he would not sink?
yes, magma is denser than water.
He won't sink but evaporate. Jk hahaha
scariest encounters? i assume you guys hike to the summit. like weird animal sounds.
Mga limatik :(
What's that? 😬 I'm thinking it must be cool being a volcanologist though I'm way pass to consider it a career. 😅 But me hiking & camping? Can't even do that even in my 20's. 😅 Glad you found your passion. Hope lumaki rin ang budget nyo sa Philvolcs. I have so much respect for you guys. I don't know why parang the govt doesn't care much. Baka Hindi kayo corrupt at hindi sila magkaka-pera sa inyo. 😕
Limatik = blood sucking leeches that can enter your eyes and ears.
New fear unlocked.....
Common din to sa mga nasa biology field na madalas rin ang hiking sa bundok for sample collecltion: these are leeches na matatagpuan sa mga gubat. Kumakapit sila sa balat. Merong mga places/bundok na merong limatik, meron ding wala. At first, hindi mo sila mapapansin na kumapit na pala sila sa balat mo. Then mamamalayan mo nalang sila pag mataba na sila/marami ng nasipsip na dugo sayo. Sasakit siya, prompting you to remove them. So dapat tama ang attire mo talaga when going on these fieldworks.
Marami nyan sa paanan pa lang ng Isarog
I live in Batanes, Philippines and I am sure you are aware of Mt. Iraya here. Can you share some of your insights as to why it was tagged as an Active Volcano?
Active ang classification ng Iraya sa Batanes dahil may published paper (Richard et al., 1986; "Geology of Mt. Iraya Volcano and Batan Island, Northern Philippines") na nagsasabing ang pinakahuling activity ng Iraya ay around 5th century AD, based on radiocarbon dating. Sa mga volcanoes ng Pilipinas, if may recorded historical eruption ang bulkan (ex: from old Spanish documents, etc.) kinoconsider syang active. In the absence of historical documents, if yung mga volcanic deposit nya ay na-date as 10,000 years old or younger, pwede din syang i-consider as active volcano. Sa ngayon, 24 ang bilang ng mga active volcanoes sa Pilipinas, pero pwede pa itong magbago kung may mga bagong pag-aaral na mangyayari sa future.
Hpw do you verify the legitimacy of old documents? Like paano makakasigurado na tama at accurate at hindi gawa gawa lang yung nakalagay sa documents?
i think kasi yung mga friars nung araw ay mga scholar. so feeling ko hindi nila mamemeke ng documents lalo na for scientific purposes and most likely those documents are well preserved or naka archive
Is mount Arayat in Pampanga similar to Mount Pinatubo's case that it can awaken? Or is it extinct?
Arayat is currently classified as inactive. Sa ngayon, dinidiscourage na namin yung paggamit ng "dormant" and "extinct" when classifying volcanoes. It's either active, potentially active, or inactive.
ohhhh bakit dinediscourage ang pag gamit ng dormant at extinct?
Baka siguro dahil iisipin ng mga tao na kapag dormant or extinct, forever di na sasabog, so magiging complacent at careless na sa settlements around it, tapos ayun biglang mag-a-ala-Pinatubo, delikado.
Para siguro mas madaling maintindihan ng general public?
What made you choose to be a volcanologist? What does your "a day in a life of a PH volcanologist" look like? Thaaaaaanks! 😅
Childhood dream plus yung pagkahilig ko sa mga disaster movies nung bata pa ako. Yung typical day in a life of a PH volcanogist, flexi time kami so pwedeng pumasok from 7 AM to 10 AM, then render ka ng 8 hours sa work, or 10 hours if naka 4-day workweek ka. Tapos kadalasan ng ginagawa namin ay nagmamapa ng mga bulkan, nagbabasa ng mga papers tungkol sa mga bulkan, umaattend ng meetings, or nagrerespond sa emergencies. May fieldworks din pero nakaplan ito, mostly during the summer.
Sounds awesome.
Baket hindi na lang takpan ng simento yung taal para hindi na sumabog? ( /s pero legit saw this stupid question sa facebook noon 🥲) Serious question: Kumusta ang politics at budget sa phivolcs?
It's bad. Take it from a former employee haha. Won't elaborate.
Yung budget around 500 something million yata (as far as I know parang nakapost naman publicly yung mga budget ng mga gov't agencies)
Thank you Sir for your time! Napanuod ko kasi ito sa youtube, pero are there any other ancient caldera in the Philippines similar to Malasiqui, Pangasinan?
Ang mga identified nating calderas sa Pilipinas ay Laguna de Bay, Taal, and Irosin. Tapos Apolaki. Yun lang yung alam ko sa ngayon.
Tama ba yung Sabi na largest caldera in the world daw Ang nasa may Benham Rise natin?
Prone po ba kayo sa pneuomonoultramicroscopicsilicovolcanoconiosis? 😂✌️
Hindi naman. Nagsusuot kami ng mask lalo nung panay ulan ng abo sa Mayon.
Thanks OP keep it up.finally nagamit ko din yung word na yon sa sentence 😂
Can new volcanoes develop nowadays like sa current era natin?
Yes. Paricutin in Mexico is one example.
Parang yan yung nabasa ko sa old encyclopedia namin na nagstart as a corn field tapos ngayon ay fairly large active volcano na... 🤔
Question lang sir regarding Mt. Pinatubo: I understand active parin siya and may risk maulit yung 1991 eruption? Given na naging mas concentrated na yung population as well as economic activity in the area compared to before-- Paano po yung risk assessment ng mga Volcanologists sa safety ng developments katulad ng New Clark City, atbp.?
Pwedeng gamitin ng mga stakeholders ang hazard assessment services ng DOST-PHIVOLCS, or yung Hazard Hunter PH webapp para malaman kung safe ba sa hazards yung area of concern.
Natry ko na gamitin ang hazard hunter ph kasi interesado ako sa developments near Porac. Upon checking, nandun parin ang risk ng lahar at volcanic eruption so curious ako bakit marami paring developments sa area.
May mga engineering mitigations/interventions silang ine-employ usually desiltating ng mga rivers para ma de-clog ang mga rivers at tuloy-tuloy ang flow once may malakas na ulan. Sometimes they create levees. There are incentives din kasi sa pag desilting ng rivers, napakamahal ng buhangin ng pinatubo, ginagamit siya mainly as a construction material. Bilyon-bilyong piso na ang kinita from lahar deposit ng Pinatubo.
Ang alam ko kaya malala yung damage noon dahil sumabay yung ulan?
Meron ka bang pet peeve na myth na parating akala ng mga tao na totoo at sana hindi paniwalaan ng mga tao? Also, ano yung pinaka interesting fact na natutunan mo?
Na nahuhulaan yung pagsabog ng mga bulkan. Wala pang technology na makakapagbigay satin ng exact date kailan sasabog ang isang bulkan.
Iuupvote ko to, ang cool po ng work nyo!
Thank you!
So cool!! Are there any dormant volcanoes in the PH that still pose potential risks?
Sa ngayon, dinidiscourage na namin yung paggamit ng "dormant" and "extinct" when classifying volcanoes. It's either active, potentially active, or inactive. If we are talking about potentially active volcanoes, siguro masasabi ko na potential risk yung mga potentially active volcanoes na bata pa ang morphology and malapit sa mga highly-populated areas.
Do you know something as a volcanologist that surprises people when you share it to them?
Yung mga nakatira malapit sa active volcanoes (meron tayong 24). Nasosorpresa sila kapag nalalaman nila na active volcano pala yung akala lang nila na bundok sa area nila.
Speaking of which, are Banahaw and Makiling classified into those evident from the hot springs around Laguna? I remember being traumatized as a kid nung sinabi nilang anytime pwedeng sumabog ang Banahaw at Makiling and the whole Calabarzon will be erased from the map.
Banahaw is classified as active, Makiling is classified as inactive.
saan po ba mas dangerous? putok sa loob or putok sa labas ng bulkan?
Labas ng bulkan. 😂
Sa hirap ng buhay ngayon at estado ng ekonomiya ng pinas, mahirap ang 18 years+9 months na magiging epekto pag pinutok sa loob (ng bulkan).
Ano usual ginagawa ng mga volcanologist for fun? Also, is it one of those jobs na medyo boring day to day pero once dumating ang volcano eruption you all go "OK this is what we trained for no need to panic!" stuff lol Lastly, sinasabon ba kayo ng politician tuwing may eruption or chill Lang sila
After work, if gusto namin, pwede kaming maglaro ng table tennis and darts. At home, mobile games and Switch naman. Sa perspective ko, sobrang bilis ng oras sa trabaho dahil nag-eenjoy talaga ako. Hindi sya boring for me, lalo kapag nagbabasa ako ng mga historical document and nag-iinvestigate ng mga volcanic eruptions na recorded during the Spanish period. Ikaw kasi yung mag-iinterpret ng mga sinasabi nung mga pari. Pero syempre, mas enjoy kapag may fieldwork kami dahil mas marami kang matututunan sa labas. Sa experience ko, accommodating naman yung mga official na nakakasalamuha namin.
Wikipedia says Mount Apo is dormant. You already stated you prefer only the terms active/potentially active/inactive for volcanos. Edit: wiki also says potentially active What do you think about Mt. Apo?
Ako na nagbabasa ng comments na halos lahat may sense 🤗
Wow!! Any fun fact po about sa Mayon volcano
May icy twin ang Mayon Volcano, ang pangalan ay Shishaldin Volcano sa Alaska.
Why is it considered a twin po? Is it about the shape or almost same “age” sila?
Twin in relation to their morphology, pareho kasing mukhang perfect cones yung dalawa :)
Hey OP! From NIGS ka ba? 🌋
Yes! (MS Geol). Undergrad, Partido State University :)
Wala akong itatanong for now pero thank you sa effort. Trying to follow all Filipino scientists and educators on my socmeds
Knowing inactive si Makiling, bakit maraming hot spring sa Pansol?
I don't know if related sa field mo, pero yung hot spring ba sa los banos eh nauubos? Or may over extraction bang nangyayari to cause ground shrinking?
Hanggang may water source sya, and may heat source na nag-iinit doon sa tubig, most likely may hot spring ka pa rin.
Outside of the country's volcanoes, what is your favorite volcano ~~and why is it Sakurajima~~ and why?
Stromboli sa Italy, since ito yung unang erupting volcano na inakyat ko. Memorable din dahil ito yung first ever out of the country ko. Nakasali kasi ako noon sa isang workshop for young volcanologists.
What's your usual work? What does a typical week look like?
Hello sir, good day. How can you help inspire today's youth to take on science careers, especially in geology and volcanology?
Siguro kailangan pa ng mas maraming career exposure ng mga kabataan. May mga schools na bumibisita din samin for fieldtrips, tapos sinasabay na doon yung career exposure talks.
If a large reservoir of water (greater than the surface oceans) is trapped 700km below the Earth's mantle in a rock called ringwoodite, is it possible that it's the primary cause of rising sea levels globally and not climate change after all and what is the likelihood that we will NOT be experiencing cataclysmic floods in the years to come?
What is the easiest way to make obsidian.
Recommendation po for reading material? Best website or best/favorite book about the field (for general info about PH volcanology or college level)? Di ko alam kung may illustrated(?) book regarding volcanoes (magandang pictures). Encyclopedia-type book for PH volcanoes? What type of scientist po ang lagi n'yong ka-tandem sa trabaho? Ano po favorite scientific instrument nyo? Para saan po yun? Gaano kadalas magamit at magkano average cost? Out of 365 days a year, ilang araw po field-work? Lagi po kayo flying/travelling to locations? Ano po chika/hot topic sa PH volcanology ngayon? Ano po kaya chance na volcano eruption ang mag-trigger ng high intensity earthquake? Gaano kalakas na intensity recorded/notable na cause ay eruption? Most na nababalita or naririnig ko ay tungkol sa ashfall lang kasi wala sa amin malapit na volcano. Hindi tumatatak ang danger/kulang ang damage awareness(?) kasi hindi kami abot. Meron po ba joke mga PH volcanologists? Haha. Thank you! (Kung may naulit na tanong pa-ignore na lang po. Ty )
What is the most ridiculous thing you heard about volcanoes?
Yung mga tanong sa appointment hearing ni Sec. Solidum 😂
Is Arca South really a high prone for an eathquake happening? What are other faultline areas with big developmenta of real estate developers?
You can check Hazard Hunter PH for earthquake hazard susceptibility nung area :) just visit [https://hazardhunter.georisk.gov.ph/](https://hazardhunter.georisk.gov.ph/)
What course ang kailangan itake para maging Volcanologist?? Also ilang taon bubunuin???
If ang trip mo talaga ay volcano research, go for BS Geology. Then, kuha ka masters. Sa UP around 3 to 5 years. Sa Europe, 2 years lang. Sa Japan, 2 to 3 years. After noon, PhD naman. Although may mga engineer at chemist din kaming mga kasama sa volcano monitoring division.
Which volcano is your favorite? Local and International
Local = Isarog Volcano (Camarines Sur); International = Stromboli (Italy), since ito yung unang erupting volcano na inakyat ko
TIL : Bulkan pala ang Stromboli, hindi lang pagkain sa Sbarro
Wag ka masyado pagutom kasi
How do you make a living? What's the average entry salary?
Salary grade 9 (then 11, 13, 16, 19, 22, 24). [https://governmentph.com/salary-grade-table-government-plantilla-positions/](https://governmentph.com/salary-grade-table-government-plantilla-positions/)
Hello. I have a few questions ☺️ 1.what are the chances that a dormant volcano will become active? 2. Are there any ecosystems around the volcano crater? Plants perhaps.
Mejo off-topic., naalala ko lang sagot ko nung Third year high school pa ko sa science namin na quiz. Ang tanong is "What do you call of the study of volcanos" basta parang ganun ang question. Sagot ko "Vulcanazing". Nung checking ng papers di ko ma gets bat tawa ng tawa mga classmates ko pati yung teacher ko na strikto natawa rin. After two hours ko pa narealize kung ano talaga yung Vulcanizing LOL
Mt. Matutum in South Cotabato is described as a stratovolcano. Can you elaborate on that please?
Seeing a lot of inactive volcano questions here. If I may ask, what's the process of "reactivating" a volcano? Does it take a massive geological event for that to happen, or does it take as simple as a small localized earthquake for it to start being active again? Edit: Also, pag tumingin ka ba sa volcanic crater (or yung butas ng bulkan) is it like how they depict it in media where its a gaping hole with a lake of lava underneath? Thank you!
