On Saturday afternoon there was a magnitude 4.1 earthquake on a normal fault that runs along the east flank of the Toiyabe Range near Austin Nevada. This fault has been the source of multiple large surface rupture events in the last 10’s of thousands of years.

Each earthquake serves to widen the Basin and Range a small amount, moving Reno farther away from Salt Lake City. This small earthquake did the same in a very small manner. www.seismo.unr.edu/Events/main....
