There's a great little book about it you can probably find at the library, by John Clague, but basically 10K years ago the Lower Mainland was pressed down about 1 km or so by glaciers, and they started to melt. Since then, the plate has been rebounding upwards, explaining the former higher sea level.

There’s plenty of proof of global warning in the past - seashells in the Grand Canyon & AZ desert, palm fronds in Iceland ice cores, etc.Here in WA state we have the scablands in the East when a huge glacial wall broke and walls of water, carrying huge boulders from miles away, covered the whole territory. It took until 1950s for geologists to figure it out. Fun to find these things out when we get older.

@@carolmiller5713: You're talking about the Missoula Floods - where 10,000+ years ago an ice dam in Montana repeated formed and broke up to 25 times by some accounts. Each cycle would create a massive lake that would create a flash flood across Idaho and Eastern Washingtion when the dam would break. The cycle repeated at an estimated 55 or so year cycle.

@@rhymereason3449 Yes. I watched some computer reenactments before I went there and it was really interesting to imagine. I guess a scientist back in the 50's put out that theory & everyone laughed at him!

closed dead clam shells on top of Mount Everest. When a clam dies it opens but these are all closed as if to say instantly buried. Did you know you can fit every continent on the planet in the Pacific Ocean alone and they are what five oceans. It's been estimated if you flattened the mountains and Rose the ocean Basin the water would cover all the globe for about 2 miles deep. And that's evidence of what we have around us ATM

Everyone needs an emergency plan, evacuation plan, trouble is, in a huge crisis that could occur, it could be sudden and it won't do much good. The Earth goes through many changes and will again, floods, earthquakes, tsunamis, avalanches, mountains moving on the ocean floor that can cause massive floods on land, even a meteor or asteroid could cause an extinction like that which killed the dinosaurs 65 million years ago! That seems like a long time, but when considering that Planet Earth is 4, 1/2 billion years old, it wasn't that long ago! Out of 1500 volcanoes, 500 are active and the latent ones could become active again and erupt, and most everything will have died out enough to cause another extinction the 6th mass extinction of the earth, IF Yellowstone doesn't blow and cause the 6th mass extinction first. But we humans of our species have only been on earth for about 200,000 years. Who knows what can happen in our future! We have satellites, sensors all over the world, and the possibility of destroying an asteroid or meteor headed for Earth (if it isn't too big!) but that won't stop another ice age or drought, or flood if it wants to happen, or 1500 volcanoes setting each other off all over the world, latent and active! There's not much we can do about that or climate change but the latter is possible if we quit polluting our air! But we can't stop another ice age or massive flood or sinkholes from happening! We bomb mountains to release snow but that didn't help Nepal and areas around there when the earthquake set off Avalanches on Mt Everest in 2015! It can happen on many other mountains as well. Probably the biggest threat is huge calderas erupting like Yellowstone and a few others whose eruption could cause a cloud that would block the sun! Then, in time, without sun, plant life will die, then the grazers who live on it and the crops that feed people and mass starvation would ensue. So what can we do? Elon Musk can only take a few people on his spaceship to Mars, and human life can't last there anyway! We need Earth's gravity or we will lose bone, muscle and brain tissue! So we better stop the 83 million more people on Earth every year from over-populating Earth, and take better care of our Planet that we have here!

@@MJLeger-yj1ww How do you propose that we stop the 83 million infants? I'm with you, we have to do something! I've spent the last 22 years researching this planet of ours only to discover that the Earth isn't as wonderful as depicted by the so called experts. My discovery? Every living creature on this planet always ends up dead, from one generation to the next,..all end up consumed by the planet. Obviously, there is something seriously wrong with this planet in that as Morrison stated ' no one gets out alive. ' But where do we go, that's the question,...after careful consideration, well, I'm hoping for Neptune. Mercury and Venus,..too hot. Mars is too close,,,,and besides red is a hostile color. Jupiter and Saturn, the shadows from the rings would no doubt drive one to insanity, and as for Pluto - ferrgeddaboutit - not a chance, too small, too far. Neptune,...that's the planet - no deaths reported to date from Neptune.

@@cordellscott Fine! McDonalds will help you to reduce the population in time before your tribe reaches middle age!

Before Katrina, the people of New Orlean's looked upward as the boats passed on the Mississippi River. They knew DAMN WELL that a major hurricane could and would take out the city. The majority did next to nothing. It will be the same when the Cascadia goes. Like New Orealn's, you will hear a chorus of survivors complain about how the "government" did not save them when it would be basically their own responsibility to prepare or (better yet) move out of the danger zone.

I'm on top the mountain... I am safe. for now.

I wonder if the Nez Perce were around in 1700 to see it happen?

@@MrManfly Many native tribes in the PNW told tales of gods fighting in the sea and this resulted in a huge wave that wiped everything out on the shoreline and they never built their villages on the coast again.

@@nikolaisikes6245 Another interesting thing about the native's stories is that they almost always described the earthquake as occurring at night when the villagers were going to sleep. Tsunami records from japan would correlate to a Cascadia earthquake that occurred at about 9 pm, just as the natives have told in their traditions. Pretty interesting in my opinion.

You should be good on the hill! I live down by the market, all silt land! Only renting, lol, probably headed inland in near future, ha

Thank you kindly for doing so. I remember I was on Vancouver island. 3rd floor in a apartment. I felt my 1st quake. scared me good i ran for the door my friend purposly blocked me lol telling me " just stay injoy it lol " crazzy guy

You remember the 2001 quake? Wild

The January 1700 cataclysm was far more catastrophic than the fake experts imagine - dozens of historic documents tell us the horror - when the next one comes - almost all of North America will be destroyed.

@@SoulfulTruth whats a 1700 cataclysm ? what do you mean ?

@@savagex466-qt1io Seismologists tell us what you see in this link - but dozens of independent historic records from c1700 tell us it was a cataclysm that destroyed an entire continent and nearly destroyed almost all of North America with colossal tsunami waves and the eruption of thousands of volcanoes: www.google.com/search?q=january+1700+cascadia+earthquake&rlz=1CAPPDO_enUS819&oq=january+1700+cascadia+earthquake&aqs=chrome..69i57j0.13955j0j1&sourceid=chrome&ie=UTF-8 In other words, seismologists do not understand the 1700 Cascadia quake and their forecast for the next one is also all wrong - the decimation will be far worse - and it's coming soon.

On the other hand, the earth settles down as it cools, which is what gives man a chance to exist.

@@krane15 It settles, but it will take quite a while yet to stop for reasons too complicated to explain in a youtube comment (but not that much more complicated to learn). To expect the tectonic plates to just stop is ridiculous, and if it had stopped then we would be in much bigger trouble as well, since quite a bit of the heat transfer from the earth is due to this.

Think it wasn't till the late 1960s that shifting plates was actually accepted as more than a theory. Check out the Rockies were formed.

Unchained, the ground will drop on the coast not really anywhere else. Tsunamis will go inland not much further than thought by scientists. You see, science goes by evidence, not by paranoia.

@@jollyandwaylo New Coastline a coming!

@@jamdwn1946 Could you expand on this thought? You might know what you are saying but I can't read your mind from this far away.

@@jollyandwaylo The thing about tsunamis is that they ricochet off one coastline onto another. They can be very unpredictable. We have lots of islands and fiords in this area.

@@bluewaters3100 They really aren't that unpredictable if you know where the quake is centered. For instance, there is no evidence to suggest that a tsunami will hit Seattle when the big quake hits the coast.

I think the town was called Mito

the whole PNW will be affected by the earthquake but only coastal areas will be hit by the tsunami as well.

The question really is when will it happen again?

I wouldn't even play Jenga in a place like that... it could go at any second

@Henry John lol not really. It’s happened repeatedly over hundreds of thousands of years it’s 100% going to happen again. The earth doesn’t just stop doing it’s thing because we’re here 💀

Lovely area for sure. I'm moving to the Oregon coast this year, we'll see how that goes.

You might be kin to Chris Farley. SNL. And other great movies!

Pretty sure there were people there before your settler ancestor, if that's what you're saying. Just a thought. Apologies if you're indigenous.

🤣🤣🤣

I believe u n it is very unfortunate

Yes it will happen again. It’s a matter of when not if. Probably in the next 200-300 years but possibly some time sooner

they've dug down far enough to find something like 18 sand layers and therefore know full Cascadia rips happen every 500 years but there are also partial rips (also huge and devastating) around every 300 years - more so on the southern end of the plate boundary. So basically any time ....

How did that work out?

Why would there be lahars, which are volcanic mudflows? Does an earthquake inevitably cause a volcanic eruption? Where would these eruptions be?

Sharon I

The 9.0 that hit Japan is very similar, according to there records a major tsunami hits the east coast about every 900 to 1,000 years. Its just part of living on the Pacific Rim. Same with the US, West coast a major fault rupture will happen, we should start preparing now by building more highways to get people away from the coast, building larger concrete buildings on ball joint foundations, putting up flood gates inland to stop or slow a tsunami. We can spend a billion dollars now or Trillions of dollars after the disaster hits.

JSandusky69, I think she's conflating two different things, one of which is the consequences of Mt. Rainier erupting. The whole Sea-Tac area is built on the debris from previous eruptions, but as I said, a totally different event.

Nothing's "overdue" these things aren't cyclical. They occur on average every x years. But the chance of them occurring at a given instant is independent of the last occurrence. "Every 1000 years" just means 0.1% chance per year in this instance.

That's what it sounds like. That time when European colonists were discovering America, and Dinasaurs walked the earth.

100 miles inland, and no where near a Cascade volcano, esp not Mt Ranier

Earthquakes are the planet’s way of saying hello. The plates gotta move, cause the magma tells them to.

No? We were on the other side of the country in 1700, we wouldn't have a clue that it happened at the time. And the Indians living there at the time didn't have a written language for another 100 years or more.

Yes that's how they know the exact date and time it happened, Japanese written records. The PNW event in 1700 caused "an orphan tsunami" in Japan - a tsunami that came from nowhere, without the preceding local earthquake that usually accompanied tsunamis in Japan.

Probably because we are more aware of them. None the less - yes.

East coast

That isn't what will annihilate the West Coast of America, the eruption in the Cascade Fault will be responsible for that! But San Andreas and Hayward Faults could happen on land causing what the Cascade will do in the ocean! And if Yellowstone caldera blows, the whole world will be affected and the 6th mass extinction could ensue! Planet Earth is very active! It has been for 4, 1/2 billion years and will continue to be active!

@@MJLeger-yj1ww Does that make my life more meaningful?

I Don't know where I'm a goanna to go, when the Volcano Blow.

@@Jabootie-oz1cb If you mean Yellowstone, there's NO WHERE you can go, it will cause the 6th mass extinction. I live fairly close so I will be toast, but as that ash cloud crowds out the sun, plants will die and then those that graze on them, crops will die and those who eat them (us) so aircraft won't even be able to fly as the cloud will envelop Earth rapidly! Kiss the world goodbye, then, perhaps in a few million years, other life will begin. Or maybe aliens will decide to come here since all the evil, warring humans are gone, and make use of this planet!

i think it was 4 out of 5 stars

Bob Wiley, I was not aware of a fault line along the north US. Do you have a map or article. If it is a fault it is extinct or inactive since there isn't much seismic activity along there.

The New Madrid Seismic Zone (/ˈmædrɪd/), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the southern and midwestern United States, stretching to the southwest from New Madrid, Missouri. When it goes there will be a lot of destruction.

Calvin Hodgson It is a different kind of fault line. It is pulling apart, rather than overlapping. I don't know exactly everything about it. I haven't studied it. I was just interested and read some things. Also the terrain is mostly dirt and mud along the Mississippi River. There are earthquakes, but they are deep within the earth and are not often felt. If you look at an earth map you can see it. From Greenland through the Great Lakes and south near the Mississippi River into the Gulf of Mexico through Panama and over into the Pacific Ocean side if south america.

You are talking about the North American craton, not so much a fault zone. It runs dowm thru the old Appalachians into TX, then back up thru NM in the Rio Grande rift valley, then thru the Rockies int Canada.

David Crandall that’s really scary. I live in Blytheville Arkansas and there have been quite a few earthquakes in this region. One a few months ago shook my house I was asleep it scared the crap outta me. Scared a lot of folks around here. My biggest fear is being asleep and a sinkhole opening up and swallowing me

Lady, no, it isn't overdue. I know your desire for doom porn makes you wish you could see people suffering but you're probably going to have to go elsewhere in the world but you have lots of choices since you want to watch people suffering.

@@jollyandwaylo um well we r over due

@@Dummmy999 Again, NO, we are not overdue. I don't know where people have gotten that meme but it seems popular. We have just now entered the period of the shortest interval between the large quakes. We are hundreds of years away from being 'overdue'. The area off of northern California seems to slip about twice as often as the Pacific NW part of the fault, so they might be overdue but not the portion of the fault off the Pacific NW.

@@jollyandwaylo from what I've seen there is no real interval, it could be another 300 years or 20 years.

@@miguellopez3392 I don't know what you mean by 'real' interval but I was speaking of the intervals between large earthquakes on that fault line. Yes, it could occur at any time but it is by no means, 'overdue'. People seem to want a catastrophe or at least they seem to want to imagine one.

the science shows it stays lower

Me being grateful I live in the midwest

Living in California seemed terrifying to me even before I watched this.

@@lilbrig6016 The Midwest actually has a pretty high earthquake risk because of the New Madrid seismic zone, which generated several magnitude 7 and 8 earthquakes in the 1800s.

and it happens again in indonesia

Philip Messina sorry your father does not control the earth quakes any more then it controls the weather.

When half of your government is conspiring to overrule your rights, then I would say conspiracy awareness is prudent for anyone not looking to be another statistic. If you don't accept the fact, then you are misled. Too trusting.

@Charles Fleury II You will find 80% of the science today politically motivated if for nothing else funding. Climate change is the prime example that you would know. Democrats are not giving out money to disprove it. The breeding habits of the African toad is political. Prime example of a dogooder bringing a species in to solve a problem and getting out of hand. Fla. Is overrun by these things in certain areas now, and they are trying to eradicate them now. People in New York don't want their money spent on a toad that doesn't affect them....political...Do you follow?
