Earthquake Swarm in NV

I have been checking the My Earthquake app several times a day since I got it and I noticed that nearly every day there are small (Up to 4.XX magnitude) quakes in northwest Nevada by Gerlach.

I tapped into the Google to find that geologists are giving this some attention and that there are other people that find this activity unusual because it is a swarm that has been ongoing since summer 2014.

Some scientists think it may be connected to building pressure in the locked Cascadia subduction zone. It is just a theory and hopefully we will find out more as time goes by and geologists study the area. Seems that scientists can't quite rule out volcanic activity as the cause versus tectonic activity.
