Assuming they are real, there was a pair of M4s 9 minutes later at Geysers area, and 5 minutes after that a 3.4 in far southern California. I wonder if the 4s were triggered by seismic waves (although the P and S waves would have gotten there quicker than that).

Might be interesting over the next day or so...or maybe not.
No focal mechanism yet on the usgs page.
tornado watch here in the heartland.
I was going to make fun of you Californians last week because Tues-Weds it was sunny and mid 80s while you were getting rain...almost record warm, but not quite.
