5.4 Quake Hits So Cal

2010-07-08 - 00-13-25UTC - 32_34_-118_-116I first suspected an earthquake might have been happening when I felt a tiny shaking while I was sitting at my desk. Then some stronger shaking occurred and I looked at my Twitter stream. All my friends in L.A. were tweeting “EARTHQUAKE.” It was good as confirmed.

Of course, it’s not really confirmed until a seismologist at USGS has reviewed the quake findings:
