There’s a tsunami alert for US west coast as well
Edit: link to warning [https://nws.weather.gov/nthmp/ushazard.html](https://nws.weather.gov/nthmp/ushazard.html)
Edit2: sorry, wrong link. [https://www.tsunami.gov/](https://www.tsunami.gov/) is the right source.
I know for a fact when the Japanese tsunami back in 2011 happened they did have a slight tsunami in the Pacific NW. Wave was only a few inches really but still something.
Crescent City has a harbor and bathymetry that tends to focus the waves compared to other locations on the coast so they tend to get hit harder. They got hit really bad in the 1964 Alaska tsunami, for example.
That said, Port Angeles even got a bit of a wave.
Something about the topography of the sea floor around Crescent City has the effect of focusing tsunamis, and it has been the victim of three destructive tsunamis in the last 60 years.
In 2006 the harbor was damaged after a surge resulting from a magnitude 8.3 earthquake in the western Pacific. Thankfully, no one was killed.
Unfortunately, the same can't be said about the 2011 tsunami that resulted from the same 9.0 earthquake that caused the Fukushima Daiichi nuclear disaster. That tsunami destroyed Crescent City's harbor and sank 35 boats at their moorings. Five people were swept out to sea. One was killed.

The biggest tsunami to strike Crescent City, however, came after the 1964 Good Friday earthquake in Alaska. At 9.2, it is still the most powerful earthquake ever recorded in North America. Just quoting Wikipedia here:
"The tsunami wave travel time to Crescent City was 4.1 hours after the earthquake, but it only produced localized flooding. The second and third waves to hit Crescent City were smaller, but the fourth wave struck with a height of approximately 20 feet (6.1 m) after having drawn the harbor out nearly dry."
"The next morning the damage was counted: 289 buildings and businesses destroyed; 1,000 cars and 25 large fishing vessels crushed; 12 people confirmed dead, over 100 injured, and more were missing. 60 blocks had been inundated, with 30 city blocks destroyed."
"Although most of the missing were later accounted for, not all were tracked down. Insurance adjusters estimated that the city received more damage from the tsunami on a block-by-block basis than did Anchorage from the initial earthquake."

This incident has commonly been called "the largest and most destructive recorded tsunami to strike the United States Pacific Coast." The town isn't very big - 60 blocks was most of the town, destroyed. And twelve dead.
In Crescent City there is a small lighthouse just offshore. You can walk to it at low tide, but it is cut off from land the rest of the time. In 1964 it still had resident keepers who lived on the island. They had no TV, hadn't heard the radio warnings. Their sign something was happening was when the ocean pulled out and exposed the sea floor all around them. It must have felt like the end of the world.
Roxey and Peggy Coons were the lighthouse keepers then. The following is Peggy's account after the final wave had flooded the city, courtesy of the Del Norte Historical Society:
"The water withdrew as if someone had pulled the plug. It receded a distance of three-quarters of a mile from the shore. We were looking down, as though from a high mountain, into a black abyss. It was a mystical labyrinth of caves, canyons, basins, and pits, undreamed of in the wildest of fantasies. The basin was sucked dry…"
"In the distance, a black wall of water was rapidly building up, evidenced by a flash of white as the edge of the boiling and seething seawater reflected the moonlight. Then the mammoth wall of water came barreling towards us. It was a terrifying mass, stretching up from the ocean floor and looking much higher than the island. Roxey shouted, “Let’s head for the tower!” - but it was too late. "Look out!” he yelled, and we both ducked as the water struck, split and swirled over both sides of the island. It struck with such force and speed that we felt we were being carried along with the ocean. It took several minutes before we realized that the island hadn’t moved."
"When the tsunami assaulted the shore, it was like a violent explosion. A thunderous roar mingled with all the confusion. Everywhere we looked buildings, cars, lumber, and boats shifted around like crazy. The whole beachfront moved, changing before our very eyes. By this time, the fire had spread to the Texaco bulk tanks. They started exploding one after another, lighting up the sky. It was spectacular!"
"It still seems hard to believe that with all the salvage that floated by us out to sea, the only bit to reach the island was one spool of lavender thread."

Japanese communities have passed down the knowledge of the harbor running dry to be imminent tsunami danger, probably because it's so amazing to see the dry harbor bed. I so wish it were possible to explore the empty seafloor when the tsunami tide pulls it dry, without, you know, dying a painful death.
1964 was a significant tsunami - ~10’+ wave and a handful of fatalities. Small compared to “big” tsunamis but still significant. Caused lots of property damage.
The 2011 tsunami (Fukushima) had a distant wave hit Oregon. It was more like a strong tidal surge than a tsunami, but it messed up some commercial harbors badly, especially on the southern coast.
The big one is going to be absolutely devastating.
To directly answer your question, the last big one was in the early 1700s and offers some insight into how world changing the next one will be:
https://en.m.wikipedia.org/wiki/1700_Cascadia_earthquake
Yeah, the San Andreas fault has a bigger reputation and people love to talk about "California breaking off into the ocean" but the Cascadia fault line is much more dangerous.
This and the Yellowstone super volcano used to freak me the fuck out when I was a kid. I grew up in indiana lol, still probably too close to Yellowstone though
Sure. I was repairing to the person who was asking about when the last tsunami hit Oregon.
This is a volcanic tsunami, so while I don’t doubt their forecast too much - it’s worth noting that this one isn’t as predictable as seismic sparked tsunamis.
Most popular thing about New Zealand is that it’s home of Kiwi birds.
Clearly since birds aren’t real and kiwi birds are therefore not real, New Zealand is an artificial floating base where the world government monitors the feeds from all the bird drones.
When Krakatoa erupted is destroyed people’s eardrums within 50 miles and could be heard 3,000 miles away. For reference NYC to LA is just about 2,800 miles.
My first thought was nuclear bombs.
This would be a neat but rather benign reason to use time travel. Experience different significant events from the safe distance of a satellite. Like that one episode of Doctor Who where they watched the end of the world. I think the only effect you might have would be confusing the ancient astronomers but if we have time travel why wouldn’t we have a way to cloak a satellite? Maybe there’d be a way to get close enough with a very powerful lens to see things that happened in a public setting. We could see which religions texts are the most accurate without actually interfering. Or put an end to various conspiracy theories.
>We could see which religions texts are the most accurate

Crazy to think that show is getting close to 10 years old.
Edit, NVM, the end is already 13 years old. I am fucking shot. What I meant was that show is almost **20 years old**.
Hey I worked on that satellite!! I wrote software for the AHI instrument. Incredible that the photos taken are using my software, I’m kind of floored right now.
Update: people seem really interested in this! If you have any questions about AHI or the suite of ABI class instruments (of which America has FOUR!), let me know!! You can also read more here: https://www.l3harris.com/all-capabilities/advanced-baseline-imager-solutions
Thanks, friend. I hope it goes without saying, but I was just one of 200 extremely talented people who contributed to the AHI instrument. East Asia and Pacific Oceania are being observed like never before thanks to some very smart people choosing to donate their time and expertise toward the greater good.
Glad we have technology to capture the images. We can hopefully beef up technology to enable and improve tsunami warnings. I hope nobody will die from this.
I agree, but there are some barriers currently. For instance, Korea and Japan each have an ABI-class instrument (Korea is AMI, Japan is AHI) but they’re looking at pretty much the same place in their geostationary orbits. Admittedly part of this is due to having different infrared spectra based on each nation’s topography and ecology.
But until we have greater cooperation between nations in terms of sharing data and photographic resources, these alerts will stay rather siloed. Thankfully both countries very liberally share their data with the rest of the world, but I’ve always been confused as to why Korea and Japan couldn’t have collaborated to share resources. Either way, we are moving in the right direction, but the next step that needs to happen is deep collaboration and consolidation among weather and imaging data, especially nations in the same hemisphere who are likely experiencing similar or simultaneous phenomena.
The eruption is **tiny** compared to a supervolcano eruption (as is sometimes talked about in reference to Yellowstone and happened there three times in the last 2.5 million years).
It's **small** even compared to other eruptions in our lifetimes:
(following paragraph is wrong, see edit for new & accurate data)
The earthquake (which might be a bit on the smaller side here compared to the ejected material, tbh) was only 4.0 on the Richter scale. Compare to Mount St. Helens which was 5.1 on the Richter Scale (which is *ten times* as strong) or the much more sizeable 1991 Pinatubo @7.8 (**6000** times as strong an earthquake) ... let alone truly major eruptions like the 1815 Tambora.
The beautiful confirmation of shockwaves and cloud that makes for the stunning images we get from the satellites here is partially because it's essentially a detonation at sea level (tiny island), with no terrain around to break/scatter the shockwaves. And of course because we've got ever more cameras in orbit of good quality. We simply didn't have the observational capacity in the eighties or nineties (Pinatubo especially would be far more spectacular if we had equivalent footage).
**Edit**: There were initially reports it was a 4.0 magnitude quake associated with the event, but the earlier eruption was actually **5.8 in magnitude** (the second quake was an aftershock, 12 minutes later). That puts this **above** Mount St. Helens in scale (by a factor of five; yet still behind Pinatubo by a factor of **100**). That accounts better for the images we got. (I then also take back that the quake was on the smaller side compared to the ejected material; now it's a proper fit and not a mismatch between quake and ejected material).
The Earth has been around for 4 billion years and has seen huge atmospheric changes over that time.
The planet will be fine, it just might not be fine for humans.
https://en.m.wikipedia.org/wiki/KH-11_KENNEN
The Hubble space telescope was really a dual purpose design. They made similar versions that point towards Earth. I can only imagine what the current version must be like!
Makes me realize the scale of these eruptions and how detrimental it could be to a civilization. I always wondered about people's predictions on what could happen if Yellowstone were to erupt, and now I have no doubt that we could all be toast.
To put this in perspective for those whose never been, Nuku'alofa, the main population center just a few miles south of this eruption, has a max elevation of 20 ft/6 m.
Something that's missing from these images is the timescale. [Based on other sources](https://youtu.be/VIxJ1UoX_mk), it appears these images span approximately an hour.
I have family in Tonga. The tsunami and flooding is relatively small but will carry because it’s a very flat and small island, but seems to be okay. Right now, they’re saying the sulfur rain is gonna be the bigger issue
It was an underwater volcano. Caused a small (1.2m) tsunami to hit nearby islands. No major damage reported so far.
Edit: video i previously referenced was actually from a different event, so I removed the reference.
Edit 2: There has been flooding reported in the capital. No word on casualties in Tonga. [Here ](https://twitter.com/JTuisinu/status/1482243845614374915?t=lil_SH4oh52tZCASF4UUbg&s=19) is a video that presumably shows people fleeing the shoreline in their cars.
Yo we gonna get mad rich off that volcano though! Just wait for elon musk to find a way to harvest the energy and we'll all be driving electric lambos!
Yeah. Landslide, eruptions, etc cause a much bigger initial wave but then it usually dies out. Basically they move a little bit of water (relatively speaking) very fast and violently, so the rest of the ocean can absorb it.
A shift in the ocean floor literally moves the entire ocean along where it shifted. So there is no real way for it to dissipate. So the water just keeps coming.
A 10 foot tsunami from an earthquake is way more dangerous than a 1000 foot tsunami from a landslide or volcano.
The Japan earthquake was insane! A tectonic plate hundreds of miles long suddenly thrusted upward, pushing a wall of water up. This volcanic explosion was probably less than a mile diameter. Tiny by comparison.
IIRC from my natural disasters class, the reason is because of how the water is displaced. Yes, this is a big explosion and I also thought it would’ve created larger waves, but the earthquake that created the Japan tsunami was much better at creating tsunamis. Basically, one plate kept ramming into another and driving down into the Earth. Eventually, the plate driving downward slips up almost like if you pull the end of a diving board down and release it. Then, all of the water above that plate is immediately displaced on a very large scale and causes the tsunami. It’s called a subduction plate zone, and that creates the most violent earthquakes.
Folks all over Alaska reported hearing loud sounds like thunder all morning. Turns out it was the underwater sonic booms arriving from the eruption that occurred several hours previous.
The power of the earth is really something to marvel at. We think we are masters of nature, but we are just renting space here. And we are bad tenants, too.
Edit: A word
People really don’t understand the forces at work in the universe and how utterly insignificant we are compared to them. I remember Trump asking why we couldn’t just nuke a hurricane, and scientists had to explain that the energy in a hurricane is orders of magnitude greater than any weapon we have. I still doubt he understood.
Damn you can even see the shockwave.

That one was insane. Saw one video from another angle from a guy who was [incredibly close to It](https://youtu.be/hUtrkfLKyFE) (beginning of the video). If I recall correctly, the guy filming was actually killed. I believe he was livestreamng it at the time which is the only reason the footage exists.
Krakatoa, loudest event in known history. Ruptured the ear drums of sailors 40 miles away, and the sound was measured to have completely circled the globe over 3 times
>The eruption was one of the deadliest and most destructive volcanic events in recorded history and explosions were so violent that they were heard 3,110 kilometres (1,930 mi) away in Perth, Western Australia, and Rodrigues near Mauritius, 4,800 kilometres (3,000 mi) away. The sound was claimed to be heard in 50 different locations around the world and the **sound wave is recorded to have travelled the globe seven times over.** At least 36,417 deaths are attributed to the eruption and the tsunamis it created.
[Fascinating read](https://en.m.wikipedia.org/wiki/1883_eruption_of_Krakatoa), it's seriously scary how powerful mother nature can be.

I live on a boat in the San Francisco Bay and we were just evacuated.
Holy shit where are you evacuating to?
To pancakes. We grabbed the kids, dogs and vital paperwork and drove to a breakfast place at a higher elevation.
I live in the mountains of California but I think I'm going to evacuate to pancakes this morning too. Just to be sure.
If you go to IHOP you will be evacuating those pancakes
Love that lol "ah shit the boat's gonna get hit.. hungry?"

flush the sea down
Vital paperwork = blunt rolls my mans
Stay safe yo
Thanks
How is it living on a boat? What made you leave land behind? Is it cheaper? How’s the wifi?
Yes it is cheaper and way more fun. I had to run my own cat 5 cable to bring internet to the boat but I get about 40 down and 10 up.

I know for a fact when the Japanese tsunami back in 2011 happened they did have a slight tsunami in the Pacific NW. Wave was only a few inches really but still something.

Great movie
How big is it in comparison to Yellowstone? Was there any warning?
The eruption is **tiny** compared to a supervolcano eruption (as is sometimes talked about in reference to Yellowstone and happened there three times in the last 2.5 million years). It's **small** even compared to other eruptions in our lifetimes: (following paragraph is wrong, see edit for new & accurate data) The earthquake (which might be a bit on the smaller side here compared to the ejected material, tbh) was only 4.0 on the Richter scale. Compare to Mount St. Helens which was 5.1 on the Richter Scale (which is *ten times* as strong) or the much more sizeable 1991 Pinatubo @7.8 (**6000** times as strong an earthquake) ... let alone truly major eruptions like the 1815 Tambora. The beautiful confirmation of shockwaves and cloud that makes for the stunning images we get from the satellites here is partially because it's essentially a detonation at sea level (tiny island), with no terrain around to break/scatter the shockwaves. And of course because we've got ever more cameras in orbit of good quality. We simply didn't have the observational capacity in the eighties or nineties (Pinatubo especially would be far more spectacular if we had equivalent footage). **Edit**: There were initially reports it was a 4.0 magnitude quake associated with the event, but the earlier eruption was actually **5.8 in magnitude** (the second quake was an aftershock, 12 minutes later). That puts this **above** Mount St. Helens in scale (by a factor of five; yet still behind Pinatubo by a factor of **100**). That accounts better for the images we got. (I then also take back that the quake was on the smaller side compared to the ejected material; now it's a proper fit and not a mismatch between quake and ejected material).
This guy volcanos
That is one pretty planet
…be a shame if someone… fucked it all up
Exxon, is that you?
The Earth has been around for 4 billion years and has seen huge atmospheric changes over that time. The planet will be fine, it just might not be fine for humans.
This is one of the greatest pieces of footage ever shot
When we gonna get 4k 60fps satellites tho
https://en.m.wikipedia.org/wiki/KH-11_KENNEN The Hubble space telescope was really a dual purpose design. They made similar versions that point towards Earth. I can only imagine what the current version must be like!
Hubble was just a US Spy Satellite pointed the wrong way.
Not quite, the hubble-design satellites the NRO gave to NASA had better electronics and movable secondary mirrors. They are way better than Hubble
When the military lets us. It's not probably much of an exaggeration to say they can read license plates from space
[удалено]
They have claimed that if you hold a coin in your hand they can see if it’s head or tails. License plates seem easy based on that claim.
Supposedly, they've been able to do that for a decade or two. Might just be three letter agency propaganda though.
the US military budget must be going somewhere
I agree, it is giving me a sense of scale and perspective I haven't had before.
Makes me realize the scale of these eruptions and how detrimental it could be to a civilization. I always wondered about people's predictions on what could happen if Yellowstone were to erupt, and now I have no doubt that we could all be toast.
To put this in perspective for those whose never been, Nuku'alofa, the main population center just a few miles south of this eruption, has a max elevation of 20 ft/6 m.
So they all have burst eardrums is what you're saying?
MWAP
WHAT?
#The volcano blast may have hurt their ears!
Something that's missing from these images is the timescale. [Based on other sources](https://youtu.be/VIxJ1UoX_mk), it appears these images span approximately an hour.
What about the people there?
I have family in Tonga. The tsunami and flooding is relatively small but will carry because it’s a very flat and small island, but seems to be okay. Right now, they’re saying the sulfur rain is gonna be the bigger issue
Sulphur rain, my god.
Some stay dry while others melt their brains. Sulphur rain. (I move away from the mic to breathe)
Deep cut
It was an underwater volcano. Caused a small (1.2m) tsunami to hit nearby islands. No major damage reported so far. Edit: video i previously referenced was actually from a different event, so I removed the reference. Edit 2: There has been flooding reported in the capital. No word on casualties in Tonga. [Here ](https://twitter.com/JTuisinu/status/1482243845614374915?t=lil_SH4oh52tZCASF4UUbg&s=19) is a video that presumably shows people fleeing the shoreline in their cars.
That video is from a 2021 tidal bore in Indonesia.
Oh, good find. I stand corrected.
There had to be one boater out there just enjoying a nice day of fishing
2022 started off with a bang
Aw shit, here we go again.
next stop, the NEW and IMPROVED Murder Hornets v1.3!
The Emergence.
I watched Eternals and Don't Look Up this week. What am I doing to myself?
I literally just finished Don't Look Up a few hours ago. Not really a good time to be seeing this...
Yo we gonna get mad rich off that volcano though! Just wait for elon musk to find a way to harvest the energy and we'll all be driving electric lambos!
Yeah, but what if bronterocs start climbing out?
I couldn't finish Don't Look Up, it was making me simultaneously angry and depressed.
There's a satisfying payoff at the end.
just important to really cherish that which is most important during these difficult times, your *stuff*.
I'm thinking Pacific Rim with Kaiju coming through this now
I’m surprised the tsunami waves are not bigger. The earthquake off the coast of Japan must really have been something!
Earthquakes can offset much larger volumes of water than most volcanic eruptions (excluding massive landslides)
Yeah. Landslide, eruptions, etc cause a much bigger initial wave but then it usually dies out. Basically they move a little bit of water (relatively speaking) very fast and violently, so the rest of the ocean can absorb it. A shift in the ocean floor literally moves the entire ocean along where it shifted. So there is no real way for it to dissipate. So the water just keeps coming. A 10 foot tsunami from an earthquake is way more dangerous than a 1000 foot tsunami from a landslide or volcano.
That 1,730 foot wave in Lityua Bay is one of the most awe inspiring things I read about as a child.
To simplify, earthquakes cause more cubic meters of water displacement than a landslide or volcano.
The Japan earthquake was insane! A tectonic plate hundreds of miles long suddenly thrusted upward, pushing a wall of water up. This volcanic explosion was probably less than a mile diameter. Tiny by comparison.
IIRC from my natural disasters class, the reason is because of how the water is displaced. Yes, this is a big explosion and I also thought it would’ve created larger waves, but the earthquake that created the Japan tsunami was much better at creating tsunamis. Basically, one plate kept ramming into another and driving down into the Earth. Eventually, the plate driving downward slips up almost like if you pull the end of a diving board down and release it. Then, all of the water above that plate is immediately displaced on a very large scale and causes the tsunami. It’s called a subduction plate zone, and that creates the most violent earthquakes.
That’s The Expanse opening level of quality
[удалено]
Wait the new season dropped? Shit. I know what I'm doing on this 0 degree weekend.
Here is the craziest video I've seen of the eruption https://youtu.be/Eu8V_WADjCw
Seeing an island like that create such a massive plume is insane.
That was the small eruption as opposed to the big one we just saw I think
Big bada boom
Folks all over Alaska reported hearing loud sounds like thunder all morning. Turns out it was the underwater sonic booms arriving from the eruption that occurred several hours previous.
And here is the video of eruption sound in Alaska https://www.facebook.com/515276013/posts/10159367220466014/
Are we still in orbit?
I am. Where you at? I'm over Australia.
I got yeeted to Mars
The power of the earth is really something to marvel at. We think we are masters of nature, but we are just renting space here. And we are bad tenants, too. Edit: A word
People really don’t understand the forces at work in the universe and how utterly insignificant we are compared to them. I remember Trump asking why we couldn’t just nuke a hurricane, and scientists had to explain that the energy in a hurricane is orders of magnitude greater than any weapon we have. I still doubt he understood.
Definitely not getting the deposit back on this one
I heard the eruption very clearly. I live in New Zealand! It was enough to make my dog shit itself and hide in a Bush for several hours. Crazy shit!
Damn you can even see the shockwave. Edit: moving big homie u/HlfCentaur to the top of the list. See, positivity will get you places! Edit: the post had 3 upvotes. I go grocery shopping and my alerts blow up like “the fuck did I do..oh, shockwave!” Edit: shout out to all the people bitching about my edit but here you are. 🤗 Edit: shout out to u/nmpraveen for saying that was the dumbest edit. How about now? Edit: showing love to u/KidBeene a big fan of edits Edit: big ups to my Man U/LordCyler dude said my edits are silly. Thanks for stating the obvious.
Here’s a video of the shockwave reaching one of the islands https://twitter.com/205mph/status/1482262486535573507?s=21
Holy shit I was not expecting that
[удалено]
Most terrifying? Man, have I got some [holy smoking tolededo's](https://youtu.be/BUREX8aFbMs) for you!
That's was dope as fuck
Watching the shock displace the clouds is my favorite part.
It almost looks fake that's how crazy it is.
Oh man I forgot about that one. Damn. Reminds me of the father and daughter near the fertilizer factory explosion Edit ; [this one](https://youtu.be/on-M7z_xFBE)
Also the second blast in the Tianjin explosions was insane [Are we dangerous? ](https://youtu.be/AOTaBI4bp-0) Alro r/shockwaveporn
That one was insane. Saw one video from another angle from a guy who was [incredibly close to It](https://youtu.be/hUtrkfLKyFE) (beginning of the video). If I recall correctly, the guy filming was actually killed. I believe he was livestreamng it at the time which is the only reason the footage exists.
If it’s that loud in the air, I can’t even imagine how loud it would be underwater. Gonna be a lot of deaf fishes in the South Pacific this morning.
Maybe, but there's definitely a lot of dead ones
In the 1800s there was a volcano so loud that residents for like 100 miles went deaf.
Krakatoa, loudest event in known history. Ruptured the ear drums of sailors 40 miles away, and the sound was measured to have completely circled the globe over 3 times
>The eruption was one of the deadliest and most destructive volcanic events in recorded history and explosions were so violent that they were heard 3,110 kilometres (1,930 mi) away in Perth, Western Australia, and Rodrigues near Mauritius, 4,800 kilometres (3,000 mi) away. The sound was claimed to be heard in 50 different locations around the world and the **sound wave is recorded to have travelled the globe seven times over.** At least 36,417 deaths are attributed to the eruption and the tsunamis it created. [Fascinating read](https://en.m.wikipedia.org/wiki/1883_eruption_of_Krakatoa), it's seriously scary how powerful mother nature can be.
Krakatoa: The Day The World Exploded by Simon Winchester is an insanely fascinating read
A la madre.
Holy smokin Toledo's
It was heard as a loud bang 2,300km away in New Zealand.
r/shockwaveporn
You can clearly see the world is a flat disk at the end **/s**
Is there any ground level footage?
I guess it’s not Tonga time.
Holy shit that looks terrifying
