Fun little earthquake

[hrj]

Just had a mild little earthquake about five minutes ago. (After all, I had to go fill out a form at "Did You Feel It?" before making a blog entry.) Nice strong shake -- about 3-4 seconds (ok, probably less, since I was counting from memory). No damage here. Ah, it's come up on the USGS site -- 3.7 and just up east in the hills. Can't tell from the map whether it was the Hayward fault or one of the lesser-known ones.

Updated: It was on the Hayward fault.
