Tree rings have always got the receipts, man. I'm half convinced at this point that tree rings could tell me where I left my car keys.

the fact that scientists used trees to determine both the year of the earthquake in this video as well as the year in which the norse arrived in what is now Canada is honestly mind-blowing to me

Absolutely fascinating. It blows my mind the ways that scientists have developed to read the past.

Native peoples in NE USA have stories handed down about the earthquake and tsunami. They’re fascinating. Also, you should have used pictures of the Marina District houses in San Francisco after the Loma Prieta Quake (World Series quake, Bay Quake 89) to show the results of liquefaction.

Once a year I go on a Cascadia fault line deep dive. This morning was it, and then this came up! Thanks for the good info as always!

Stuff like this really rocks my world.

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?

Hank, I really like your writing and presentation style. Humorous and very clear, explaining even complicated subjects in an entertaining and understandable way.

Liquifaction Photos were from the Christchurch NZ earthquake, I lost my garden path in that quake. It's still there, just buried from the liqufaction

Two earthquake related videos in a row... If there's a third, I'll assume you're trying to warn us about something.

I remember seeing sand blows in Indiana when we lived there when I was a kid.

0:40 I'm hoping that you are referring to the lower 48 because I'm pretty sure Alaska's 1964 Good Friday Earthquake (9.2) was a megathrust and stronger than 1700 Cascadia Earthquake (9.0).

Local oral history also corroborates the January 1700 date.
