Nick Zentner has some of the more entertaining explanations….here’s one.

Waterbobber. That’s a good one, need to watch it again. Maybe later today. Thanks for posting.

FYI - Nick Zentner has many interesting talks/videos on NW geology, Tsunami, eruptions, and floods. Search for his name on YouTube. If you ever get the chance to see a talk in person from him it’s well worth it.

You should read the fine print. I used to have the same rider with StateFarm. Until I found out your home has to be like I can’t remember 70 or 80 or 90% destroyed before you can collect anything. So for example, $90,000 worth of damage? Screw you.

Maybe you have something better than what I was able to negotiate.

I Don’t have it. I looked around for something though. I’ll be screwed like the rest of you.

The new houses that get built in our neighborhood in Astoria are built on a bunch of piling driven into the earth 20 feet or so. Must be so there’s a better transfer of the shaking from the ground to the structure above. What engineers can dream up boggles the mind.

I think it’s to better protect against liquefaction of the soil, as with movement everything turns to jello.

WB. Yea but the shaking will be so bad the liquification is the least of their worries. The ground is mostly sand fill on top of whatever is below. Those piling will look cool sticking out of the ground with the house scattered in pieces all around them.

Well, if anything close to a 9.0 hits, it likely won’t matter. However, It likely would help during smaller shakes, as has already been proven in in California. If the piling is designed to sway a bit during a quake, energy is dissipated.

Some perspective on big quakes. The 1906 San Francisco earthquake had 23” of movement along the fault, at least in some areas. Forgot where we were, but was showed a fence that had the 23” fooset from the quake.

Google pics of the Alaska 1964 quake for the flavor of a 9.0. There was a lot more than 23” of movement!
