I remember having read in an old National Geographic magazine article about New York's Central Park that some rocks there were a sign of an ancient big earthquake. And that they meant another big earthquake was going to happen in New York, eventually. Chilean here. As we have quakes on a daily basis, architecture is meant to resist them; even the ancient one was. How could a city like New York withstand even the lesser of the big earthquakes?

Now that is a rhetorical question. There would be major damage and loss of life. That would be the case on the Gulf Coast, too. When I trained to be on a Community Emergency Response Team, a civilian auxiliary for first responders, the text we used had a chapter on earthquakes. I saw pictures of pancaked floors in buildings, and where there might be survivors, and decided I was fine with just the hurricanes and mass shootings.

@@robertfaucher3750 The statement was "...So officially, the United States has never actually had an earthquake like this in its history..." I was pointing out that the statement could have been worded a little better. True, the Pacific Northwest was stuck by an earthquake and tsunami before the US existed (1776), but there has been a an earthquake and tsunami of similar nature that occurred since (1964, Prince William Sound, Alaska). The US has the Cascadia and the Aleutian subduction zones. I thought it would be important to make that explicitly clear the lower 48 has not had and earthquake like this in its history.

@@OmuYasha1990 They were explicitly talking about the West coast, including diagrams of the Jaun De Fuca and Cocos plates. Since they were only talking about an earthquake on the West coast, it is entirely accurate to say there hasn't been an earthquake "like that" since the country was started. Just how important is your clarification, anyway? Is anyone going to be humiliated in life or fail a class because you didn't offer that distinction? You said it was important to make explicitly clear... so who is theoretically saved from trouble by your kind offering? What situation is a person going to be in where they need this important information to be explicitly clear? Or is the answer no one, and you just like to feel smart? I guess the second part.

A quake on this fault would be devastating for the coastal communities, but people who don't live here often don't understand that the major PNW cities are not on or near the Pacific Ocean coast. A magnitude 9 out on the fault will not be felt as a 9 in Seattle, Tacoma or Portland. An 8 on the New Madrid fault by the Mississippi River would be far more devastating in overall damage, imho.
@simpleanswer8954 2 жыл бұрын
So what? That tsunami is still going to come right in the Puget Sound. There would still be enormous damage. Meanwhile the largest recorded earthquake in Mississippi was a 4.7. "IMHO" your comments about a 9.0 happening in Mississippi are based on fantasy, while the idea of a 9.0 on the West coast is guaranteed eventually. A 4.7 out here is so common no one cares.

And no I'm not talking about how it will compare it to the 1989 earthquake that well I was only a one year old when that happened and was definitely quite massive, but I'm talking about in comparison to I think it was 1906 which was even bigger and was incredibly devastating. When's the next that big one coming because it is expected pretty much at any point

"...the United States has never actually had an Earthquake like this in its history..." The 1964 Alaska Earthquake was a subduction zone thrust earthquake with a moment magnitude of 9.2, and there have been others of about the same magnitude in the Aleutians, (1946, 8.6Mw, 1957, 8.6--9.1Mw, and others) though, being in the Aleutians, they didn't cause anywhere near the damage of the Good Friday Quake, which, in turn, would pale in comparison to what a Cascadia quake, in the much more densly populated Pacific Northwest, would do, but they have happened.

@AaronOfMpls 2 жыл бұрын
@@aiko9393 Yup, carbon-14 atoms are constantly decaying with a half-life of about 5700 years, and constantly being created by cosmic rays hitting nitrogen-14 atoms in the atmosphere. This creates a (nearly-)constant proportion of carbon-14 relative to the usual (stable) carbon-12. And since living things are continually exchanging carbon with the atmosphere (directly by breathing, and indirectly through food they eat), their own proportion of C-14 stays about the same as long as they're alive.

That story originally came from a video from someone(a doomsayer) who also says Yellowstone Volcano, which has erupted several times in the past, will destroy all of North America in our lifetime, even though all the Geological evidence of past eruptions show that is clearly not the case. The West Coast of North America has had major earthquakes in the past (as this video and others shows) and will have them in the future, yet The West Coast is still here. The Juan de Fuca plate has been sliding under North America for tens thousands of years and will continue to do so until it is totally gone, which will not happen for tens thousands of years from now. Yet the West Coast of North America is still here.
