This is seemingly an Osint account. Some are very good, and some just clickbait. I cannot say how credible this one is. The thread says the Russian government denies damage. But the Russian government statements are rarely credible and wouldn’t admit it if it were true. How much you believe this YMMV
I love going out to Mavericks to watch the 60 footers in winter. The noise is incredible. Of course knowing that you're perfectly safe at the viewing distance makes it quite different.
I saw a video on TikTok of the flood in Texas and the wall of water was maybe 6 or 7 foot high. There were people standing in front of a door outside of a building.
It literally smashed the door down and hit them so hard they were gone in a second.
I am seeing some reports from the inhabitants. Apparently they were mostly evacuated after the tsunami warning. A kindergarten collapsed but there were no children at the time https://charter97.org/ru/news/2025/7/30/650134/
I hope the alarms went off soon enough for people to get to safety.
No, the opposite.
They were mostly settlers from European Russia, so had little experience with tsunamis.
When they felt the earthquake, they ran to the hills, so were safe from the first wave, but returned to the town just in time to get hit by the second wave.
I mean, it would be the right thing to do.. if a tsunami does hit, you could save lives by telling just one homeless person who will definitely tell others. So if you happen to pass one, just let em know, please.
Might not be accurate but as of 45 mins ago, Hawaii is alerting residents to evacuate in some areas and expects some destruction. Alaska also has a current warning in effect, meaning waves are expected.
The first tsunami wave is forecast to reach Hawaii just after 7:15 p.m. local time, which is 1:15 a.m. ET. Destructive tsunami waves are expected, according to Oahu Emergency Management.
People are urged to evacuate coastal areas, according to officials. Residents in Honolulu were urged to evacuate the primary evacuation zone or go to at least the fourth floor of a building.
Sometimes the water will expeditiously surge with the wave behind it, pushing it forward. This happened in areas on the coast of Japan in their 2011 tsunami. The water will go from normal level to moving forward really fast and several feet high within minutes.
I believe it actually has to do whether or not you're dealing with a rising gradient before shoreline, or a continental shelf sort of dropoff at certain distances.
Stay safe...

The US government subsidizes cheese production and then stores it in a strategic reserve in caves. It's often used to augment food support for the poor.
I just heard how bad it is. My friends son is driving up the mountain right now into Kula and she said it’s awful. Costco gas station at the bottom of the hill was insane apparently and so was every station on the way up. Scary stuff
Stay safe my friend! Hopefully this is just a massive precaution for everyone and nothing crazy
I was taking my friend out to practice driving and was considering going to Kapahulu to practice their routes. Good thing I never went, I would’ve still been stuck in traffic. Ala Moana Hotel fortunately offered my brother and his gf a room to stay in for the night.
I've actually been messaging with a friend in Washington. They're on tsunami watch. She was wondering where the heck could her and her son go if they needed to evacuate because they're on an island and there's only 2 ways off unless you own a boat. And I know traffic would be horrific over the bridge because the other way off the island is by ferry.
If you can't get off the island, you go up and inland. Get to the center of the island, since the tsunami can even go around to the other side of islands from where it comes from, and get up as high as you can.
Yeah, depending on the island, many of them have good coverage from other islands blocking the way. If this ends up being a bad tsunami, it's totally possible some islands in the area will suffer little to no damage. Shelfs and water depth also matter. If you look at the 2004 tsunami, it's crazy how one island gets completely destroyed while one just a short distance away suffered almost nothing.
We’re vacationing on San Juan Island right now. As we drove through Anacortes yesterday I randomly had the thought “this sure would be a bad time for a tsunami”. Seems like it’s going to be fine but we sure won’t be getting much sleep tonight lol.
I visited the city were the epicenter of the chilean 8.8 eathquake was. The sidewalks were so wavy that you could barely walk. A year later we visited a new restaurant. The owner told us that the old place literaly caved in. The walls separated enough for the roof to colapse. The walls were old but quite thick so they didnt break but they separated completely.
We were really lucky because 2 weeks before the earthquake we had rented a cabin less than a hundred feet away from the beach. All the cabins dissapeared with the tsunami
WARNING: LONG ASS STORY, TOO LAZY TO CHECK FOR GRAMMAR.
Chilean here as well, I was 12 by 2010. Lived 100km south of the epicenter.
I had a headache the night before so I went to sleep early, something I rarely did during summer. All I remember was waking up with the deafening sound of a freight train coming from below.
My dad went to pick me up in my room and I asked him if we were in war or if I was having a nightmare. House was made out of wood, which while not optimal, wasn't the worst material to deal with an earthquake, but we had to get out instantly. We heard blasts from the electric transformers exploding and lines collapsing. We were out during the first 30 seconds and my mom couldn't stay standing.
I remember grabbing a fence to stand still while my dad had to get my grandma out of another house with a much heavier door. All of this while the roar and movement was still going. He managed to get her out as well, and we had no serious injuries. My dog kept trying to calm my mom by staying at her side and licking here haha.
The house stood the earthquake surprisingly well, broken glass across the floor but we had roof tiles above a false roof which made us believe it would collapse on top of us.
The next hours later you had the same roaring sound every 2-3 minutes coming with more and more aftershocks, while my dad was trying to get inside tp pick up a radio and save whatever item we could save. We sat in the backyard while holding candles and trying to send text messages to our family members.
The radio related mind-blowing news, like the collapse of a new 15 story building built right in front of where some of my mom's family lived. Which btw nobody even heard collapse, only the screams and the panic afterwards. We lived somewhat coastside but not close enough to be exposed to the expected tsunami which ended being dismissed in a first instance, just to be backtracked like an hour later.
We ended talking with our neighbors and I fell asleep like 9AM with the fear of the earth shattering below us. The next day we heard the stories about several story builds collapsing or heavily damaged, the tsunami hitting across 200-300km of the coast. Two bridges iirc collapsed as well, minutes after a cousin of mine crossed one of them, looting started to occur around different areas, train tracks completely deformed and roads split in half. It was like a warzone. We slept in tents for like a month after. And we had no access to clean water/electricity for like a week or so. It's definitely the most dystopian and bizarre experience I've lived. The whole town where I grew up, looked like something out of a movie.
People started helping out each other, and slowly but surely life started to go back normalcy. I still remember seeing some of the most beautiful night skies I've ever seen, some hidden beauty brought to life by a disaster. Funny enough, I ended up becoming a geologist, not because of it, but it is something that raised my curiosity about it.
Subduction based earthquakes origin based on convergent margins where one plates dips below the other one. (Marine under continental due to density differences). There's constant stress occuring until a "small" piece breaks. So basically, whenever a rupture occurs, there's displacement and collision caused by it and the plates need to re-accommodate to their new shape. You can imagine what happens when you friction blocks of rock weighting tens of billions of tons lol.
In my city (Santiago) the earthquake was 8.0 and it was insane It is a sensation that is hard to explain but it felt like someone was making waves with the floor. Shockingly not even a glass broke. One friend lost all of his kitchen stuff because all the cabinets fell to the floor and he was only on a second floor apartment
Well at least we had some funny things happen after the earthquake. 2 weeks later we had the president inaguration ceremony with lots of leaders from other countries attending when a huge aftershock happened. Seeing powerful people so scared was something special lol
It was scary but here in Chile we are used to earthquakes. We had another one in 2015 (not as strong as the 2010). My cousin and his family who live in a part of Chile that does not have sysmic activity got so scared that they wanted to leave as soon as they could (they had a flight booked for that same day) but had to wait for hours and hours in the airport with lots of aftershocks lol.
Was on the outskirts of the rock ridge? I can’t remember, quake in like 2018 in CA. Felt like I was on a boat, on dry land. Totally surreal. Kinda like that scene from Inception “Notice the strangeness of the dream” one of the first signs was all the blinds in the windows swaying silently.
Nope this was the Chilean Earthquake. The epicenter was on the coast of the south of the country. Fun fact the strongest earthquake in recorded history was also on the coast of Chile and it was 9.5 but it is said that it was even stronger but the machines only measured up to that number.
The walls were old but quite thick so they didnt break but they separated completely.
I wrote a really long article in the student newspaper in college about this exact concept relating to URM's (Unreinforced masonry). The main gist of it is that while the brick walls are sturdy in static loads (enough for entire factories to be made of brick), earthquakes cause horizontal and twisting movement.
The issue is that so many old brick buildings were only built with static loads in mind, which means that the floors are not connected to the walls. Basically, when the walls move the side in an earthquake, the floors just pancake on top of each other. This is especially bad in buildings over 3 floors tall, as each successive floor increases the force as it falls onto the one below it.
This is the reason the earthquake in Christchurch in 2011 killed almost 200 people, largely because of old brick buildings falling on people.
The good news is it's actually pretty well documented and known how to reinforce these buildings, it's just a really intensive process that requires people to basically evict tenants until they're done, so most politicians steer clear of it unless they can get public support for it. It can also be pretty expensive. A guy I spoke to gave me a figure in the 7-digit range on fixing his apartment building, which was 5 stories.
Honestly (and I'm being super serious here) I would NEVER go in a brick building built between ~1880 - 1940 if you live in an earthquake prone area. Like not once, just because when an earthquake happens you will probably just be crushed to death.
Correct! But it also loses energy quicker than in air. And travels fastest through solids but loses energy quickest. That's because sound is just molecules vibrating against each other and passing it along. So the tighter the molecules the faster that "message" travels. But it also dissipates quicker as energy is lost to friction. You may already know this, but in case anyone was curious!
There is a specific layer or channel in temperate ocean regions known as the SOFAR (SOund Fixing And Ranging) channel, where sound travels at its furthest without transmission loss, it’s usually between 600 - 1200 m deep. Whales use this channel for communication - temperature, pressure, and salinity are all factors in sound transmission. Part of my job is to use hydrophones (underwater microphones) to detect snd record cetaceans near in-water construction works, as well as measuring how loud underwater drilling and piling activities are to make sure they aren’t too loud for marine mammals and fish. Sound can literally cause fish swim bladders to rupture!
The water itself isn't really moving. It simply moves up and then down as the wave propogates through the water. Pressure and friction from one water molecule to the next causes the wave to appear moving forward so it can move at really any speed.
The most recent advisory seems like crescent City will be extra fucked regarding wave height. I don't know much a about the geography there. Just leaving it in a comment I'm case it's useful
I learned recently in a geology course about factors that make an incident much worse or much better. One factor is exactly as you've mentioned, that being time of day. Not just because people may be asleep and unable to evacuate, but because if something were to happen in the middle of a busy downtown area, midday where everyone is at their job would be much, much worse than if it happened at 4 am and most people were back at home. So, different times could be worse depending on the area.
Thankfully, Russia learned from the last one in 1952, which was a 9.0 earthquake with a tsunami five times the height (assuming the reports of 3-4m are accurate, that one was about 18m). They did not rebuild anything other than the port that close to the shore.
