I was having lunch a bit ago and I suddenly felt the table move a bit, I felt dizzy and the ceiling above the kitchen made a cracking sound. It turns out we had a 3.0 earthquake, centered south of Berkeley:
A minor earthquake occurred at 12:20:19 PM (PDT) on Wednesday, May 2, 2007.
The magnitude 3.0 event occurred 2 km (1 miles) NNW of Emeryville, CA.
The hypocentral depth is 8 km ( 5 miles).
As I said before, we lived in Berkeley for two years (1996-1998) and never felt a quake at all. We have probably had about 6 or so since we have been here.
