1915 Pleasant Valley earthquake with magnitude 7, occurred 150 miles to the southeast of the earthquake swarm
The largest quake so far is M=4.2. This is probably a seismic swarm associated with fault creep. Both nearby faults are caused by Basin and Range stretching, and are inclined (‘dip’) to the west, with very low slip rates (<0.2 mm/yr). The strain rate and seismic hazard are low, but are higher 20 miles to the west along the Surprise Valley fault. The closest large quake this century struck 150 miles to the southeast, in the 1915 M=7 Pleasant Valley event.
