In 2010 there was a 7.2 centered 30 miles south of the socal border that caused $1B of damage on both sides.

#426.4 magnitude it is a lot. I hope there are no injured
Re: Strongest earthquake in years rattles Southern California
#43I felt this (near Caltech, Pasadena). I spent the entire duration trying to figure out what was shaking my desk. I hope this doesn't trigger anything larger. Does anybody know if this was close enough to the fault line to possibly affect anything? EDIT: I see they have updated the article to a 1 in 20 chance.

I was only a few miles away in San Gabriel and did not feel a thing; I wonder if the SGV blocked any of the waves. Wish I had come to campus early today to feel that one.
Apparently, mountains buffer the waves. SGV is bordered by a San Gabriel mountain range. So, your experience sounds reasonable to me.

#44Earlier quoted context omitted.
I think the lack of damage from this shows a high degree of preparation. This same earthquake 50 years ago would have likely been much worse.
I was in Los Gatos for the epicenter of the 89 quake that was 6.7 I believe. It was pretty bad. It looks like this was handled much better.
Mind if I ask what part of Los Gatos you were in? I was near the corner of West Main and Bayview, a few blocks from downtown.
We didn't have much damage, but walking through the neighborhood afterward I counted about 20 houses that slid off their foundations.

#45>Gallegos said that the dried chiles hanging from a hook on her kitchen wall were all shaking. "It was surreal." was this really the best anecdote they could find to include in the story?
I don't know, but anyway... If you happen to be under dried chiles when they shake, be sure to keep your eyes closed because the pain could make an earthquake much more pleasant. Been there done that, and that pain lasted hours... ouch! On a more serious note, the anecdote might suggest that the earthquake produced very high frequency oscillations. Dried plants are relatively light and stiff so that a larger but slow…

What an unusual form of earthquake injury!

In the Loma Prieta earthquake Santa Cruz and Watsonville were badly damaged. But their was very little information getting out. So a lot of the coverage was San Francisco and Oakland. There is an inverse correlation between how bad a disaster is and a reporters ability to get any information.

#47I feel like we're woefully underprepared for earthquakes. It feels like pushing away technical debt on a societal scale.

#48Here's a nice USGS predictive graph of earthquake 6.7+ probability for California from 10 years ago, posted on HN a few years ago:

#49I'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...

#50Luckily, this was far from population centers - epicenter about 10 miles from Ridgecrest, a town of 30,000 people just south of Naval Air Weapons Station China Lake, and just east of US 395, about 80 miles east of Bakersfield. Informative USGS links include: https://earthquake.usgs.gov/earthquakes/eventpage/ci38443183... Select "View Neaby Seismicity" to see the 47+ recent quakes in this area.
It was pretty close to Trona. Having driven through Trona, life sucks in Trona and today it sucked a lot worse. Lots of shaking here in the greater LA foothills, but no damage (though this house does have earthquake insurance).
Ah Trona. Not much out there to be honest. Here's what the view from Trona Pinnacles looks like: https://photos.app.goo.gl/LrML8TsBbZoW79t1A
