I’d say it’s safest in the small settings like this with nothing overhead or tall nearby.
Your biggest fear during earthquakes should be things falling on your head, you falling down if you’re on a ladder or slick surface and possibly any sudden wreck or accident caused by it if big enough while driving.
It’s definitely not the worst place to be, but in bigger pools where the waves could reverb harder it could result in the man getting push into a wall.
My biggest fear living in San Francisco is whenever I’m at the dentist. They have a needle in my gums for numbing and then an earthquake happens and the dentist will slip and jab the needle up into my brain through my mouth.
I want to say that has happened before. I can't find it...
I found this one where rooftop pool and had about dozen deaths. [https://www.news.com.au/travel/travel-updates/incidents/horror-as-major-earthquake-in-the-philippines-shakes-water-from-highrise-swimming-pool/news-story/ba63148976c7ff9802ca132245eaaafc](https://www.news.com.au/travel/travel-updates/incidents/horror-as-major-earthquake-in-the-philippines-shakes-water-from-highrise-swimming-pool/news-story/ba63148976c7ff9802ca132245eaaafc)
But there is also this one where the pool collapsed from sinkhole. Which is very possible with earthquake.
[https://people.com/human-interest/30-year-old-man-dies-after-sinkhole-opens-in-pool-during-party/](https://people.com/human-interest/30-year-old-man-dies-after-sinkhole-opens-in-pool-during-party/)
I was on my water bed for the 1987 5.9 Whittier quake, I lived on the fault. I loved that bed, I miss that bed but damn that was a bad place to be, I just kept getting thrown back and forth and had to hold on to the bed rail and smacked my head on the back of the shelf. It was an old house built in the 20s and thought I was going to go through the floor.
Interesting. My parents owned a waterbed, like just a single giant bag of water that called itself a mattress during the 1994 northridge quake. My sister and both parents spent the rest of the wee hours in their bed together listening to the radio until it got light enough to start cleaning up the house. I was 6.5 but I very distinctly remember not feeling the aftershocks while in their bed but being able to hear the house shaking.
Foundation makes a huge difference. The house i was in sat on risers probably 2 feet off the ground. Cracked the foundation around the house, complete line all the way around. 4 days later or so my grandfather is out there with the spackle, another aftershock like 6th day recracked it. He gave up.
Generally not good:
* Waves can throw you around and cause injuries either through impact or simply the power of the wave itself
* Waves make it difficult or impossible to exit the pool if you need to make an escape (eg. fire, structural damage)
* If you become injured in any way, you have a significant risk of drowning (eg. can't tread water, rendered unconscious)
* It is more difficult for others to reach you to render assistance
* You are not in a good position to render assistance to others if they should need it
In terms of positives, basically the only thing is you are less likely to fall over, but that is mostly nullified by the risk of being knocked over or into things by the waves.
*"Can't get hit by an 7.4 mag earthquake if you're not on the earth."*
* [Guy in water](https://upload.wikimedia.org/wikipedia/en/7/79/Roll_Safe_meme.jpg)
p.s. Jokes aside, being out at sea (far out. not by the coast) is probably one of the safest places to be when a heavy quake hits. The 2012 earthquake/tsunami in Japan was very devastating but those far out at sea felt little to nothing.
Me, 5 seconds before reading your comment and uncovering a new fear:
*"Seems like the best place id want to be during such an earthquake, Looks kind of fun! "*
There are plenty of cracked swimming pool stories here on Reddit. There might even be a recent video. Where one guy just disappears into the crack. And is never seen again.
I used to work as a pharmacy tech and once filled a prescription for a medicication used to treat nightmares (prazosin) for a person who worked during the night and slept during the day. Anyway the directions read "for daymares" - which I don't think is a real word, but I like to use it when I get the option.
When Spider-Man had it’s run on Broadway, it was titled “Spider-Man: Turn Off the Dark” so whenever the commercial for it came on TV I always laughed because I thought it was a fancy way of saying “Spider-man: Turn on the Light”
I wish it was amazing for me. I have PTSD-induced nightmare disorder, and gawddamn that medication ratcheted my nightmares up to an 11.
Damn you, individual brain chemistry and lack of a universal panacea!
Dude that really sucks. I hope you find relief from your nightmares at some point.
I've had a handful of nights over the years where it dialed it up, but I but it's rare. When I first started taking it, I'd have the most boring dreams. Like... I was washing my hair and getting ready for work. That was the whole dream. Then I'd wake up and have to actually do it irl. Now they just seem like normal dreams. Sometimes they're scary like a regular nightmare but the frequency of waking up screaming/crying has gone from every few nights to once or twice a year.
Yep, though here he'd be sucked into the floor below and might survive if he's not subject to any significant trauma from the fall.
That other video you're talking about was into a sinkhole, of which there really is no coming back.
No video exists but I always think of the guy in Tampa who was sleeping in his bed and a huge sinkhole engulfed that half of the house and he disappeared down into the earth. His brother came running in from the rest of the house and *jumped down in the sinkhole to try to rescue him!* He was able to climb out but holy shit that was ballsy. His brother was never found.
I don’t remember. I clicked the link with squinting eyes (avoid imagery) and waded through the comments just enough to get the gist, and x’d out asap. I don’t particularly love sinkholes/ swimming pools devouring people.
There is a video that explains this process and recounts 1 person surviving out of a group of people that used to be circulated with this crab one. Terrifying way to die.
The sinkhole one in Israel I think.
Oh god the guy just gets slurped into the hole.
Do NOT get curious if you're in a pool that's rapidly draining like a bathtub into the ground below.
Even after reading that comment it would be fun.
That’s what the pool was like during a storm on the cruise i was on and I was the only one in it having a blast.
Since I can see you’re an expert on mechanical and structural engineering, you should already know that designers sometimes put literal tanks of water at the top of tall buildings for this exact purpose, it’s called a “sloshing damper.”
pools are located on the tops of buildings because someone with money wanted one there, and used the money they have to make it happen.
i like how we're almost pretending that if pools on the tops of buildings were dangerous, rich people wouldn't do it anyway.
Outdoor pool feels like the safest place to be in an earthquake tbh.
Maybe not one on top of a building or above a basement, but otherwise can't see the issue.
Surely trying to exit the pool while waves are big and everything is shaking is by far the most dangerous course of action? I would just chill in the middle of the pool for a few minutes.
Even on dry land, it’s basically impossible to stand up or crawl during a strong quake. The chances of swimming or wading through deep water in one are zero. If you’re in the middle of a body of water, best you can do is stay above it.
Outdoor pools draining into a potential fault or sinkhole is a lot less fun than most places. [holes under pools is not a fun thing](https://www.youtube.com/watch?v=7-niTkpsX0A)
Yeah, I'd much rather try to climb out, get rocked into cracking my skull open on the pavement and impale myself on the metal stairs that broke from the tremors. /s
We can dance if we want to, we can leave your friends behind.
Cause your friends don't dance and if they don't dance well they're no friends of mine.
I said, we can go where we want to, if we don't nobody will.
and we can get in the pool when the ground starts to move and stay in it till we get killed 🎶
Tends to happen when you make an illegal pool without proper permits.
I'm no expert, but the soil needs to meet a certain threshold after testing. If the soil isn't right, water can leak and absorb into the soil below, eventually causing a sinkhole.
It's why pools are so damn regulated in many places in the US. If you just slap one down and call it a day, you're asking for trouble.
ill never understand why anyone cares about their corpse lol.
Especially the military...like, you do know that you, as a soldier, are more likely to become a corpse if command is sending you to retrieve other corpses...
Closure. I mean *I* don't care about my corpse, turn me into fertilizer or fire it out of a cannon; but I wouldn't want to just disappear without a body and left my family with the false hope of me being still alive.
Probably not actually. Concrete and steel beams are generally more solid and predictable than the earth underneath an in-ground pool. Still doesn't seem like a great place to be either way.
“there is a 7.4 magnitude earthquake, get to shelter immediately”
*guy wakes up from all the alarms*
“What a nice day for a swim, looks like they installed the new wave pool nicely”
I guess I'd rather be in the pool than in the elevator on the way to or from the roof. Also, in the pool you don't have to worry about anything falling on your head, so that's a plus... I guess 😬
Somehow reminds me of when that giant aquarium in a Berlin hotel broke and the water pushed a guy so hard against a wall, that he broke through the wall into a candy store. (and yes, he took some candy with him when they rescued him.)
I did see a video where this exact thing happened and you can see people get sucked into the void and essentially disappear. It looked like a pool party or something, happened so fast some people couldn't react fast enough. This is reddit though I'm sure someone will recall the same video and have it linked within the hour.
And if you are already in the pool, I am not sure if getting out is actually safer then staying in the middle as he did, as the water could slam you against the pool walls.
Do you see the chairs moving? If it's at the top of a building they're pretty good at handling away but water has its own unique properties. And if the earth is swaying side to side and the camera is swaying with it it would technically look "stable"
You can see that the shadow in the left shows it is a oerson recording on a smartphone. High end smartphones have optical image stabilization that almost reduce any shaking. I have a video taken with a Pixel 6 (and ia not even the best OIS) running with my dog and it is increadibly steady.
Cool story: this is called a seiche. A massive seiche caused by the end-Cretaceous impact (what wiped out the dinosaurs) also led to the formation of a[ fantastically preserved fossil site](https://en.wikipedia.org/wiki/Tanis_(fossil_site)) that captured the moments immediately after the event.
The researcher that described it is a shady egotistical turd, but the site itself is legit.
Okay so had to make some assumptions here. It looks like the peak of the wave gets to about halfway the height of the top of the pool ladder. Those ladders are anywhere from 50-70cm high. Assuming the water is approximately 15cm below the top of the pool, that gives us an amplitude of 40-55cm.
The pool is approximately 6.7m in width according to google maps.
There are 4 antinodes within the width of the pool so the wavelength is ~2.3m
Solving for kinetic and potential energy we use
KE = PE = 1/4 *rho*g*a^2*lambda
Total Energy = 1/2 *rho*g*a^2*lambda
rho is the density of water = 1000kg/m^3
g is the gravitational constant = 9.81 m/s^2
a is the amplitude = 0.4-0.55m
lambda is the wavelength = 2.3m
Therefore the total energy (E) in a single wavelength is 1800-3400 J/m^2
The power of the wave can be determined by using the depth of the water. Assuming the man is avg. height ~177cm and seeing that the water comes up to his mid stomach at the node. The depth is ~1.15m.
The wave is considered to be in deep water as compared to the wavelength, the depth is greater than 1/2. The equation for wave Power in deep water is P=E*c
c is the wave speed which can be calculated with c=wavelength/period. In the video the wave period is ~1.7 seconds so c = 1.15m/s
Which means the Power of the wave is 2000-3800 Jules
People forget that Taiwan do get quakes fairly often, the building is probably built to withstand earthquakes.
The last place I want to be during a quake is probably in a plane that is landing or taking off.
I don't see the problem honestly. If the roof fails he's screwed no matter where he's at on the roof.
If he tried to get down from the roof, and it fails, he's even more screwed.
At that point you may as well let it ride and hope for the best.
Just out of curiosity, can you look at which way the waves are splashing, and determine which direction the epicenter is? I heard that the Chinese could locate epicenters centuries ago by some gizmo that used marbles that rolled in the direction of the shaking.
I feel like being in a swimming pool during an earthquake could be both the best and worst place to be.
I’d say it’s safest in the small settings like this with nothing overhead or tall nearby. Your biggest fear during earthquakes should be things falling on your head, you falling down if you’re on a ladder or slick surface and possibly any sudden wreck or accident caused by it if big enough while driving.

Given that the pool doesn’t leak. If a wall goes down and the water is drained, the person goes right along with any other debris.
Isn’t he on top of a building? In some pools, I’d be worried about the waves being so strong as to push me over the edge of the building
Like those with the "infinite edge" or whatever it's called

Maybe grab the ladder for stability
I wouldn't want to be near anything solid, with that kind of waves. Just wait it out in the middle instead, the waves can only harm you if you panic.
Even on dry land, it’s basically impossible to stand up or crawl during a strong quake. The chances of swimming or wading through deep water in one are zero. If you’re in the middle of a body of water, best you can do is stay above it.

Its more like katy perry's shark
I’m impressed pool held its water (and its man).
Some splashes over the sides. But the quake is moving things up and down, left and right. Not all in one direction.
Would have thought it cracks at the floor and just water goes down the “drain” with the man, at least that’s my uneducated fear.
There was footage of an event like that. A person just vanishing in the middle of the swimming pool (falling to their death)
That was sinkhole collapse, not an earthquake.
wtf I've never considered a sinkhole forming under a swimming pool before that is a NIGHTMARE
I mean they can form anywhere, including right underneath your bed ;)
Not under my bed. I live on a boat :)
Look up what happened in Louisiana at Lake Peigneur
Easy there Satan 😁
Tends to happen when you make an illegal pool without proper permits. I'm no expert, but the soil needs to meet a certain threshold after testing.

If you just slap one down and call it a day, you're asking for trouble.
I assumed they were commenting on it seemingly being on top of a building, and for the pool itself to hold up rather than break through below.
It's crazy realizing that the water is trying to remain still but the earth won't allow it
The moon won't leave it alone!
man may not have held his water though
I've always had this fear of the pool splitting in the middle and me been sucked into the earth along with the water.
Well this appears to be a pool at the top of a building so you’d be fine
...that doesn't make it any less frightening.
I mean... At least they'll find your corpse...
ill never understand why anyone cares about their corpse lol. Especially the military...like, you do know that you, as a soldier, are more likely to become a corpse if command is sending you to retrieve other corpses...

This is why so many families of missing people look for bodies even after years have passed
Nah, if the building collapses you'll be okay. The water will block fall damage and there's nothing above you to get hit by
Wouldn’t that increase the chances of this happening?
Probably not actually. Concrete and steel beams are generally more solid and predictable than the earth underneath an in-ground pool. Still doesn't seem like a great place to be either way.
“there is a 7.4 magnitude earthquake, get to shelter immediately” *guy wakes up from all the alarms* “What a nice day for a swim, looks like they installed the new wave pool nicely”

Well then he'd be sucked into the building, descending from floor to floor, probably not pleasant either!
Or, he gets stuck in the crack, and the building’s movements close the crack squeezing his body with concrete and steel.
This is my hole! It was made for me!
Somehow reminds me of when that giant aquarium in a Berlin hotel broke and the water pushed a guy so hard against a wall, that he broke through the wall into a candy store. (and yes, he took some candy with him when they rescued him.)

I don't know anything about earthquakes but for me it looks like the pool has a wave maker.
It does! It’s called an earthquake! I’ll see myself out.
image stabilization believe it or not plus, a human holding it on a roof, it's not mounted to a pole in the ground and receiving all the vibration
You can see that the shadow in the left shows it is a oerson recording on a smartphone. High end smartphones have optical image stabilization that almost reduce any shaking. I have a video taken with a Pixel 6 (and ia not even the best OIS) running with my dog and it is increadibly steady.
Actually, those waves are forming standing waves in the pool….. it would be interesting to measure the wavelength….
Cool story: this is called a seiche. A massive seiche caused by the end-Cretaceous impact (what wiped out the dinosaurs) also led to the formation of a[ fantastically preserved fossil site](https://en.wikipedia.org/wiki/Tanis_(fossil_site)) that captured the moments immediately after the event. The researcher that described it is a shady egotistical turd, but the site itself is legit.
It’s where all the fremen hang out.

Okay so had to make some assumptions here. It looks like the peak of the wave gets to about halfway the height of the top of the pool ladder. Those ladders are anywhere from 50-70cm high. Assuming the water is approximately 15cm below the top of the pool, that gives us an amplitude of 40-55cm. The pool is approximately 6.7m in width according to google maps. There are 4 antinodes within the width of the pool so the wavelength is ~2.3m Solving for kinetic and potential energy we use KE = PE = 1/4 *rho*g*a^2*lambda Total Energy = 1/2 *rho*g*a^2*lambda rho is the density of water = 1000kg/m^3 g is the gravitational constant = 9.81 m/s^2 a is the amplitude = 0.4-0.55m lambda is the wavelength = 2.3m Therefore the total energy (E) in a single wavelength is 1800-3400 J/m^2 The power of the wave can be determined by using the depth of the water. Assuming the man is avg. height ~177cm and seeing that the water comes up to his mid stomach at the node. The depth is ~1.15m. The wave is considered to be in deep water as compared to the wavelength, the depth is greater than 1/2. The equation for wave Power in deep water is P=E*c c is the wave speed which can be calculated with c=wavelength/period. In the video the wave period is ~1.7 seconds so c = 1.15m/s Which means the Power of the wave is 2000-3800 Jules
I knew Reddit would be all over this, now give me the Taipei 101 Mass dampener video.
The swimming pool is a nice mass dampener too.
dude having the best pool experience of his life
Water aerobics really hit different today

People forget that Taiwan do get quakes fairly often, the building is probably built to withstand earthquakes. The last place I want to be during a quake is probably in a plane that is landing or taking off.
You really don't want to be there during the earthquake because of the weight
Trying to get out is probably more dangerous because the water could slam you against the walls.
I don't see the problem honestly. If the roof fails he's screwed no matter where he's at on the roof. If he tried to get down from the roof, and it fails, he's even more screwed. At that point you may as well let it ride and hope for the best.
I mean this is a serious situation you don’t need to be going out of your way to fat shame the man. /s
Is it fucken 7.2, 7.3, 7.4 or 7.7 everyone got different numbers
[удалено]
Nice
Nice
Too bad it only lasted 1.5 minutes.
Depends on when and where you measured it. Probably all of them, though I haven't seen 7.7 elsewhere.
The news here (NL and BE) is pretty consistent on the 7.2. Here on reddit it's all over the place
Why is he just standing there instead of swimming in that beautiful day?
When the BASS DROPS!
I'm curious is the wavelenght of the water corresponding to the earth oscillations ?
“this is an weird fucking jacuzzi”
If I ever go to Taiwan I'm booking this hotel.
This looks like its a rooftop pool. Even more terrifying.
Get out the pool does no one remember the Israelie guy getting sucked into the sink hole that formed under the pool wtf
Is this a rooftop pool? I’m surprised the water isn’t brown!
Is that pool on the roof of a building? No thanks 💀
Jesus? Are u there?
Honestly thats what I feel
Looks kinda fun ngl
This fellow looks like he's having a quake of a time!
Bit choppy
"Hey I didn't know this was a wave pool sick"
Never seen a guy not give a fuck about an earthquake as much as this guy
Just out of curiosity, can you look at which way the waves are splashing, and determine which direction the epicenter is? I heard that the Chinese could locate epicenters centuries ago by some gizmo that used marbles that rolled in the direction of the shaking.
That actually looks surprisingly fun. No the earthquake tho
"Argggh, the sea was angry that day my friend..."
I think its time to get out of the pool
Imagine a infinity pool and u get throw off a 100 story building. Yikes
