Earlier quoted context omitted.

I've been watching a bunch of Nick Zentner's lectures for the last few weeks and I live nowhere near the PNW, so my case I doubt it was algo based. I have no doubt that in general you are right and the topic is "trending" (for whatever that means these days).

> the topic is "trending" In which case they might suggest it to you as well, even if your personal interests are not closely related to whatever happens to be trending?

It wasn't suggested to me. I am working my way through his lectures and I explicitly went to the channel and selected the video.

Cascadia Subduction Zone[1] is why I never considered living in Seattle/Portland once I found out about it. Funny, cause I live in the SF Bay Area, where the earthquakes are frequent, but they can never reach the magnitude of what's possible by the Cascadia Subduction Zone.

What makes you think a big one ("The Big One") isn't going to hit the Bay Area?

I’m wondering how far the big one will be felt. As egocentric as my question is, will I feel it on the East coast?

Bizarre...I just watched this video this evening. "Great Earthquakes of the Pacific Northwest" https://www.youtube.com/watch?v=UJ7Qc3bsxjI

Nick Zentner has a lot more content on YouTube too (and it's all very lovely!), see https://www.youtube.com/@GeologyNick

I don't think they're saying that.

But from what I recall reading, the big one that hits Seattle will exceed the big one that hits the Bay. Seattle's big ones are higher magnitude but less frequent. Iirc it's also likely the 9.0 that hits Seattle won't be in most of our lifetimes. The last really big one was before Europeans arrived.
