There has been an earthquake swarm in northwest Nevada. There was also a swarm in this region last August. The largest magnitude EQ so far is a magnitude 4.6. Here is a magnitude 4.0 EQ that initiated my interest in posting about this swarm. These epicenters plot along the Warner Valley and Guano valley fault zones.
Here is the extensional moment tensor for the magnitude 4.6 EQ:

I will post more on this swarm later today. check back!
