We just had quite a rattler. It's the first time I've been in an earthquake this big while I've been at work. My phone isn't working and neither is the cell, so I can't check and see what's going on at home until I leave for lunch. That's why the 1994 quake, which was pretty big, didn't scare me totally--all of us were home together and I didn't have to worry about where Len or Michael was and if they were safe.
The USGS says that it was centered near Chino Hills and it was a 5.8. That's on the other side of L.A. from us. Here's a map. The aftershocks have already been as big as 3.8 and there have been a number of them since this happened.
