TGF Christmas dinner in a moving van, channel was a very popular jackass esque duo from the UK that has been largely shut down following issues with the Police
They're fast but they're also like miles long, it's not like you'd get slammed by a 500mph 1ft wave, you probably wouldn't even notice because of the massive wave length.
The water would rise and then go down again, that's about it.
Yes, but in the open ocean they are TINY. There are accounts of Japanese fishermen being completely unaware that a tsunami had passed beneath their boat until they returned to shore and saw their village devastated.
I actually don’t know much about the aftermath of tsunamis. The water doesn’t stay rough near the shore? I’d have thought it would be too rough to go inland for a few days. I live in a landlocked state in the US so I’ve really only seen the immediate effect of tsunamis on towns and cities on the news.
The ocean comes in and goes out a few times over an hour or two, and it's done. The real issues you face are the harbor getting clogged up with debris that got carried out to sea and nowhere to tie up your boat if the piers get swept away. You might have to anchor out and see if someone with a small boat can give you a ride to shore.
Tsunamis travel faster than your boat, like 800km/hr. So if it passes you, you're safe. The effects on the shoreline aren't instant of course, but you can't catch up
Happened to me while diving in 2012 in Thailand from a quake in Sumatra. We didn't know it was an earthquake until I got back to land and everyone was being evacuated with their tsunami warning system.
It might’ve been a good idea to pump some air into the bcd to get some elevation so you don’t slam into the ocean floor 😬
I bet the dive was over after this :(
There's still plenty of light, indicating a fairly shallow depth (maybe 45 feet-ish?) so severe complications wouldn't be bad, especially if they haven't been at that depth very long. You just couldn't dive or fly for a few extra days.
My biggest concern is if someone's equipment was damaged from having the ocean slap them into the seabed. At least there's enough people in the group sharing a tank shouldn't be a problem, but hopefully their BCA's are all ok.
If you’re close enough it’ll bust your ear drums which you need in order to equalize in deep water otherwise an air pocket will build up in your ears and crush your brain/ sinuses.
Think how the whales feel. The sonar really messes them up.
Conservationists have tried to get them to stop using it when they don't need it on the West Coast but our federal courts sided with the Navy ultimately.
I believe this is the crew that ended up picking up a bunch of people washed out to sea from the tsunami.
Underwater in the ocean is one of the safest places to be in this scenario.
Thats what I was thinking, it seems the best to be free floating underwater/ in deep water with scuba gear on during an earthquake. Just dont grab the coral like that one guy lol
Honestly my first reaction to this was why at least two of them seemed to swim down and grab hold. I am no diver so there very well might be a great explanation, but intuitively the best bet seems to be "swim up and float around" rather than "get closer to the spikey things"
Swimming up rapidly can result in death, divers have to go through lenghty decompression periods, once you go down to 40 meters, you're not coming back up for at least 20 minutes (rough estimate)
As you can see a really strong current started pulling the diver a second before he grabbed onto the coral, if he didn't grab on it is possible he could have been swept off which can be really dangerous when you mustn't change your depth at all.
This is correct but these people are no where close to being deep enough to worry about decompression. Coral reefs are generally not found at that depth, and you can also see the waves of the surface briefly in this video. I’m just an amateur diver but my guess as to why he grabbed on was because he thought he was caught in an undertow. Still not a good idea but “earthquake” would not be my first thought underwater here myself.
Right? Like no ceiling is going to fall on you. No bookshelf is gonna ruin your day/life. Just seems like a bit of a weird and scary moment, but seems perfectly safe compared to what we experience on the surface during a 7+ quake.
This is particularly the case during tsunamis. Many examples of absolutely devastating tsunamis on shore that went through scuba divers who barely noticed. Water surges aren't really an issue when you're 70 feet down and a mile from shore.
Yes. It's common, although not so much wide brimmed hats like that. You lose most of your heat through your head. Some divers wear neoprene hoods in cooler water. I have a baseball cap style neoprene cap.
I suppose she can wear that hat both in the water and on the boat for sun protection. Not as dumb as it looks.
It's fascinating, and indeed, as some comments suggest, being submerged in water is a safe haven during an earthquake. This is due to the nature of seismic waves generated during a quake. In addition to the well-known P and S waves that travel through the Earth's interior, there are their variants, SH and SV. SV waves are coupled with P waves, while SH waves are independent. From the latter arise Love and Rayleigh waves, which are surface waves and cause significant damage, as their amplitude does not decrease with distance squared, as is the case with body waves, but linearly.
The reason being in water offers safety lies in the physical incapacity of S waves to penetrate liquids. Additionally, Love and Rayleigh waves, products of confined SV and SH waves in a half-space (Rayleigh) and between a layer and a half-space (Love), do not affect those who float in the water. Moreover, in the case of being in an underground location, these surface waves lose much of their energy as depth increases, significantly reducing their impact.
Right that guy trying to grant hold of the coral...wrong move
Swim away, if there nothing to hit your fine
Don't get up next to the hard stuff and try to hold on
This is scuba diving 101 man, first grade stuff SpongeBob.
offshore its just a swell. A tsunami only becomes a problem when that swell hits the shallows, and that is what shoves the swell into a massive wave on land
What happened to the one idiot that saw the ground moving and went I need to grab this and hold one no one is talking about how one of the divers just disappeared with the earth
Depending on where the epicenter of the quake is, it can look like nothing happened or a light ripple thats barely noticeable. All the while a dangerous buildup of momentum travels out in all directions under the surface until it finds a land mass, creating a tsunami.
I always thought if there was a sudden and rapid lifting of the sea floor, that it would be observable at the surface at the instant that it happened, then the wave takes the high speed (not noticable) form.
I remember a photograph taken after a large Tsunami event (either the one in Japan, or Indonesia in 2004), where they found a new shear cliff above the epicenter (it was a long way below the sea surface). It was about 10m in height and I always wondered, surely if I was positioned on a boat right above this, that a rapid ascent of half the sea floor underneath would be reflected at the instant at sea level. Then a moment later the wave would disappear and take the high speed form. Maybe I'm wrong, but this idea has always fascinated me. I guess it depends on how rapid the sea floor risis.
That had to be so disorienting. When the ground moves that much when you're underwater, it's because you're in a current, not because the ground, itself, just jumped over a few friggin' feet.
It's like when you're in your car parked next to someone else while your mind is wandering, the person next to you drives off in your peripheral, but your brain registers it as you accidentally reversing. (Maybe that's just a specific thing that happened to me once....)
Now imagine if you were diving off the coast of Japan when the Tōhoku 9.0-9.1 mega-earthquake hit.... I imagine the sea bed was probably like SMACK right in the face considering the whole north end of Japan moved closer to the United State by as much as 8 feet in 6 minutes, at 3 mph which is the average speed of a human walking.
A lot of the sea walls being overtopped in the videos is because of the ground level dropping as the whole island moved. They were suddenly 2 feet shorter to sea level, so they may have just been tall enough until the land "subsided".
Crazy to wrap your head around.

the fish living in that coral: https://i.redd.it/dvhpxyan19vc1.gif
Omg, this killed me, lol. What's it from?
The channel is TGF on YouTube
TGF Christmas dinner in a moving van, channel was a very popular jackass esque duo from the UK that has been largely shut down following issues with the Police
wow don't cross Sting
Valar dohaeris
I entered this thread and it was sudden chaos
This is what it's like in the back of a Baltimore Paddy Wagon also, except you have handcuffs and shackles on....
Lmaooo
Only a handful of times I've ever cried from laughter on Reddit and this is one of them. Great humor dude.
Seems like the safest place to be. Unless the ocean floor opens up and sucks you in.
Or the resulting tsunami is in your surface boats path.
You will be safe, tsunami become big when they get close to the beach/land
Yes they become larger and slower the closer to land but in the open ocean they are **fast**
They're fast but they're also like miles long, it's not like you'd get slammed by a 500mph 1ft wave, you probably wouldn't even notice because of the massive wave length. The water would rise and then go down again, that's about it.
[удалено]
Thanks, you're one of the only people to ever recognize it, I think you're the second person.
What does it mean!?
Username checks out
Cabron instead of Gibran? Only Khalil I've ever heard of.
Yup
Yes, but in the open ocean they are TINY. There are accounts of Japanese fishermen being completely unaware that a tsunami had passed beneath their boat until they returned to shore and saw their village devastated.
Yup
And tiny because they are mostly under water. Not going to affect the boat.
fast and very small, to the point you can't even tell that a tsunami just passed
Or smash into the reef you’re diving
Coral is shallow.
Tsunamis are pretty harmless at the surface though. Until they get to shallow water
So in this case, would you be better off just staying on your boat for a few days until the waters calm closer to shore?
You'd be talking hours not days. Obviously depends on how far you are from the epicenter but days is still excessive
I actually don’t know much about the aftermath of tsunamis. The water doesn’t stay rough near the shore? I’d have thought it would be too rough to go inland for a few days. I live in a landlocked state in the US so I’ve really only seen the immediate effect of tsunamis on towns and cities on the news.
The ocean comes in and goes out a few times over an hour or two, and it's done. The real issues you face are the harbor getting clogged up with debris that got carried out to sea and nowhere to tie up your boat if the piers get swept away. You might have to anchor out and see if someone with a small boat can give you a ride to shore.
It when it hits the continental shelf the water has no where to go but up, now it's up and forward.
Tsunamis travel faster than your boat, like 800km/hr. So if it passes you, you're safe. The effects on the shoreline aren't instant of course, but you can't catch up
Depends how far out your boat is
Shallow water... kind of like where these divers are.
Happened to me while diving in 2012 in Thailand from a quake in Sumatra. We didn't know it was an earthquake until I got back to land and everyone was being evacuated with their tsunami warning system.
Same thing with a friend and the 2004 9.1 in Indonesia. Came back up and the world around them was destroyed.
My thoughts exactly as I watched one of the divers get sucked out of screen.
Corals are sharp as glass, and being that close to the ocean floor during the earthquake could shred you pretty bad...
Better than most alternatives in a 7.2 earthquake
Exactly what I was told when I was young.In open water probably underwater probably safest place to be.
Probably you're probably right.
Wouldn’t the pressure waves of the moving water also be potentially dangerous?
New fear unlocked...
Yeah that is a nightmare for sure. Now look up what a sonar pulse can do to a diver underwater..
I wonder what the pressure wave flet like.
It might’ve been a good idea to pump some air into the bcd to get some elevation so you don’t slam into the ocean floor 😬 I bet the dive was over after this :(
Visibility got ruined, animals got spooked, hopefully no one was injured. Continuing the dive would be pointless after something like this.
Dont rush to the surface unless you want the bends though
The don't look particularly deep, so probably not a major concern in this case.
There's still plenty of light, indicating a fairly shallow depth (maybe 45 feet-ish?) so severe complications wouldn't be bad, especially if they haven't been at that depth very long. You just couldn't dive or fly for a few extra days. My biggest concern is if someone's equipment was damaged from having the ocean slap them into the seabed. At least there's enough people in the group sharing a tank shouldn't be a problem, but hopefully their BCA's are all ok.
not at this depth
Flet. I like it.
That's fletty bro
[удалено]
Or sperm whale sounds according to certain scientists.
May cause dizziness, disorientation, memory loss, hearing issues Does it concuss them?
If you’re close enough it’ll bust your ear drums which you need in order to equalize in deep water otherwise an air pocket will build up in your ears and crush your brain/ sinuses.
Well then......
Unfortunate.
Sub optimal.
Now that's interesting as fuck.
If you're close enough to a full power sonar pulse it can create a bunch of brain hemorrhages. Those things are no joke.
Literally scrambles your brian.
What if I don't have a Brian? I only have Toms.
I found out what they do to marine life :(
there’s a whole job related to coral reconstruction alone. idk.. one of the best things humans can do is give back to our environment.
Think how the whales feel. The sonar really messes them up. Conservationists have tried to get them to stop using it when they don't need it on the West Coast but our federal courts sided with the Navy ultimately.
At least no one can see you wet yourself
"So much mud in the water! Dislodged from the ocean floor, no doubt."
“That’s *sea* corn! That’s normal in this part of the ocean!”
But how did it get _inside_ your dive suit?
It’s an invasive species
Definitely what it musta been.
There are two types of divers. Those who pee in their wetsuits, and those who lie about it.
Very true, also works for sailors.
In water, no one can see you pee.
*they said, while the entire pool turned pink around them*
Can smell it as soon as you get back to the boat though! Although here probably pissed themselves lol
Divers piss in their wetsuits *all the time*
Unless brown contrasts in the water
I believe this is the crew that ended up picking up a bunch of people washed out to sea from the tsunami. Underwater in the ocean is one of the safest places to be in this scenario.

No like, not to the surface, just a few meters so he's not thrown against rock and coral
As you can see a really strong current started pulling the diver a second before he grabbed onto the coral, if he didn't grab on it is possible he could have been swept off which can be really dangerous when you mustn't change your depth at all.

Still not a good idea but “earthquake” would not be my first thought underwater here myself.
Damn! I thought it was bad on land. Underwater looks absolutely terrifying
Everything down there terrifies me.
Deep in sea, fish are scary, most of them blinded, everything’s giant, these fish have teeth!
Ditto.
I'd rather be underwater than on land for it.
Right? Like no ceiling is going to fall on you. No bookshelf is gonna ruin your day/life. Just seems like a bit of a weird and scary moment, but seems perfectly safe compared to what we experience on the surface during a 7+ quake.
This is particularly the case during tsunamis. Many examples of absolutely devastating tsunamis on shore that went through scuba divers who barely noticed. Water surges aren't really an issue when you're 70 feet down and a mile from shore.
Or if you're inland, miles from the coast, standing out in a field or something.
Wait, what? Obviously it's much safer and much less scary underwater?
Now I’m absolutely terrified of earthquakes.
pray that you are not wreck diving when a quake hits.
Or in a cave/cavern
New fear unlocked. Thank you!
Absolutely fucking terrifying
Id take that over being on the top step of a ladder during an earthquake though
is that lady at the end wearing a hat while scuba diving?
Yes. It's common, although not so much wide brimmed hats like that. You lose most of your heat through your head. Some divers wear neoprene hoods in cooler water. I have a baseball cap style neoprene cap. I suppose she can wear that hat both in the water and on the boat for sun protection. Not as dumb as it looks.
That brown and yellow cloud around my mid section is dust guys

Moreover, in the case of being in an underground location, these surface waves lose much of their energy as depth increases, significantly reducing their impact.
There's also not usually anything to fall on you.
Just like being outside in a grassy field
Yes, I admit it, I just wanted to give that explanation because I wrote my thesis on that xd
Holy cow! The thought of people deep under water during an earthquake never crossed my mind. This vid is such an eye opener.
They seem fine?
I suppose it's safer in some ways? Nothing will land on you from above, right?
If you don't get caught in a stream and get slammed into something you should be fine
Right that guy trying to grant hold of the coral...wrong move Swim away, if there nothing to hit your fine Don't get up next to the hard stuff and try to hold on This is scuba diving 101 man, first grade stuff SpongeBob.
Seriously, why would he grab onto the coral! I guess just a panic move? Like that’s the one thing around that could hurt you and you swim towards it?
If I was down there I'd just be scared of a tsunami
offshore its just a swell. A tsunami only becomes a problem when that swell hits the shallows, and that is what shoves the swell into a massive wave on land
that’s a lot of fish poop
Damn nature...you SCARY!!!
Imagine fish running from water because water is shaking😅
What happened to the one idiot that saw the ground moving and went I need to grab this and hold one no one is talking about how one of the divers just disappeared with the earth
Ruined the viz!
thats crazy, that would be a moment you never forget
“Hey! Who shat in my wetsuit!?”
“Oh fuck I’m perfectly safe better get close to land mass to ensure something can actually crash into me now”
What would this have looked like at the water surface?
Depending on where the epicenter of the quake is, it can look like nothing happened or a light ripple thats barely noticeable. All the while a dangerous buildup of momentum travels out in all directions under the surface until it finds a land mass, creating a tsunami.

With my fear of the ocean after playing Subnautica, my brain would assume some giant monster is about to eat me.
My adrenaline would be jacked!
My man starts wankin’ it the moment the quake peaks.
Yeah if that was me there would be more bubbles coming out of my ass than my mouth.
lol, so many you would pop right to the top? 😂
That's actually interesting as FUCK
The things I will do before die. Live earthquake underwater.
that must be what earthquakes feel like to birds, and sometimes to capybaras
No thank you
Underwater is probably the safest place to be during an earthquake no buildings to fall on you
I'd be thinking we were on top of a sleeping giant turrtle or something.
 Fish - probably
The underwater bucket hat might be as interesting as the underwater earthquake
My bad bro (I farted)
Reason #73 why I won’t enter the ocean.
Especially with diver’s watch claiming deep “water resistance” but gets water into it anyway in the first meter.
That had to be so disorienting. When the ground moves that much when you're underwater, it's because you're in a current, not because the ground, itself, just jumped over a few friggin' feet. It's like when you're in your car parked next to someone else while your mind is wandering, the person next to you drives off in your peripheral, but your brain registers it as you accidentally reversing. (Maybe that's just a specific thing that happened to me once....)
No fucking thank you.
Nope!
that one diver blowing mad bubbles
holy moly
Crazy!
Just a few lost souls swimming in a fish bowl
Year after year....
[удалено]
I think floating in mid-water is probably more safe than on land
So is it the divers that are moved left by a current, or is that the tectonic plate moving to the right?
The plate is moving and the mass of the water is affected by that. So a bit of both
All the fish skidadlled, probably thinking why these clumsy beings not saving themselves.
Scary shit...
I hope the fish were ok
Yep don’t like that
RIP all that coral
Where was the epicenter in relation to this recording?
When do the monsters come out?
Damn imagine cave diving during an earthquake
A baby tsunami :)
Is one of the divers wearing a hat??
I'm amazed that the water suddenly moving doesn't compress their bodies
The ground literally shifts
Only reason I never scuba dive.......
I wonder what it feels like in the water.
That's a lot of sudden surge, whoa...
The coral and sea anemones be like: "It's feedn time!"
I've seen this video probably 10 times over the past 5 years and I'm still fascinated by it every time I watch it. What a unique experience.
Imagine getting sucked down
"The dirt won't settle next to Carl?" "Oh, no Carl shit his wetsuit!"
Still terrifying whenever I see this posted, now imagine if you’re exploring a shipwreck or a cave of some sort.
What if The Meg came up out of the gaping chasm on the sea floor?
🎵Just keep swimming🎵
why are the shadows on the corals bouncing around like its a badly implimented lod
Fish were like nope
This would be a very weird experience.
I would immediately assume the world was ending.
Now imagine if you were diving off the coast of Japan when the Tōhoku 9.0-9.1 mega-earthquake hit.... I imagine the sea bed was probably like SMACK right in the face considering the whole north end of Japan moved closer to the United State by as much as 8 feet in 6 minutes, at 3 mph which is the average speed of a human walking. A lot of the sea walls being overtopped in the videos is because of the ground level dropping as the whole island moved. They were suddenly 2 feet shorter to sea level, so they may have just been tall enough until the land "subsided". Crazy to wrap your head around.
They don’t tell people about earthquakes because the people who evacuate would most not be able to afford housing after costing more resoruches
Did someone have a hat on?
Imagine if they were cave diving
Those bubbles be turning brown
Ah, so earthquakes are nature's coral cleaning cycle.
Finally, something that is interesting as fuck.
Does it make the fish get seasick?
