Yeah, very likely at some point. So far a couple of aftershocks in the area but none bigger than 1.4.

ETA: Correction, biggest thus far 2.3.

Makes you wounder if this is the "preshock" to the big one...

Same area, I take it?

 

[Be Well]

I assume that the Hayward fault runs through...Hayward? I have friends who live in Pittsburgh (shudder). I assume they'd have felt this. I will ask.

The moderates are a sign the earth is adjusting. It is when you don't have one for a while that you know things are building up.
