I'm pretty sure much of SF (marina, south beach, mid soma) are partially built on landfills are considered "liquification zones" by the city.

I think the term you're looking for is "liquefaction map" - I only know this term because we're exposed to the risk here in Charleston, S.C.: https://sf.curbed.com/2019/4/15/18311670/earthquake-map-cali...

That is scary to me. Should it be scary to me? In regards to liquefaction zones and earthquakes? I mean, i recently built a fence and the moisture in the ground made me conscientious of liquefaction when tamping for my gravel and posts, how does this play out for SF in an earthquake?

You're probably looking for the "Liquefaction Hazard Maps" page for the Bay Area: https://earthquake.usgs.gov/hazards/urban/sfbay/liquefaction...

Disclaimer: I am a geologist, but I'm not a P.G., hence all that I say on this topic is bullshit. p.s., Does your conference have beer? If it doesn't, I'm not going. I mean, I'll be so happy when AGU rolls around, because, man, I'm thirsty.

It should be scary. Soil liquefaction is one of the main failure modes of small structures in earthquakes. Take a look at the map for your area to know if it matters for you.

Parent used the correct term, a liquefecation map shows liquefecation zones.

You probably meant "land fill," not "landfills." Only a handful of things are actually built on landfills in the Bay Area, and all the neighborhoods you mentioned are built on fill. There are ships under Soma, though.

It sounds like a big quake could solve the housing issues
