That’s a pretty small earthquake for California. You’ll feel a 5.x but it doesn’t get much more than a passing blurb in the local news when it happens. Everything there is built for earthquakes, the damage doesn’t start until you get to the 6.x range.

Even at this 3.9ish we had a few things fall off shelves :)

I was lying down and felt it. Wasn't enough to get me up though as these small ones aren't uncommon.

I suppose I should earthquake proof my apartment though, you know those twist tie things that come with some furniture that are meant to be anchored into the wall? I've never used 'em.

At some point with a big one I'll have some shelving and what not fall over. But I've been over a decade here and I haven't needed them yet.

I think The City felt it more than usual because it was centered near SFO. Most earthquakes we feel are higher magnitude but further away. Commonly NE of Berkeley.

The entirety of SoMa and Mission Bay are liquefaction zones [1], expected to face major damage during the next major earthquake.

I wonder if "Drop, Cover, and Hold On" really is good advice for liquefaction zones for a very big earthquake.

What's the alternative? Drop cover and hold on at least avoids injury from attempting to move on an unexpectedly moving surface.

When the ground stops moving, then you have a chance at purposeful motion.

Those are usually to prevent furniture falling on to children if they were to climb it, etc.

One alternative might be “run as fast as you fucking can towards Potrero Hill” if you are close enough to be able to make progress towards it.

It was so close to SF that it was much more apparent than other earthquakes. For me, this was the most noticeable earthquake in SF this year.
