Magnitude 4.0 Earthquake Struck UC Berkeley at 2:41 PM, October 20th 2011 – 3.8 Aftershock at 8:16 PM

Thursday, October 20th, 2011

[Or rather, make that a 4.0 on the Richter, final answer. That was for the afternoon earthquake. This evening’s aftershock at 8:16 PM was a 3.8.]

People in the West Bay could definitely feel this this one today, the one centered beneath UC Berkeley.

It felt like a succession of sharp bumps for a few seconds and then there was some generalized shaking – perhaps it all lasted about six seconds.

The initial estimate was a 4.2:

Wouldn’t you and your kids like to ride the Quake Cottage?

Available for weddings, bar mitzvahs, etc, I’m sure.

And it’s probably cheaper than a bounce house…
