This swarm is tightly clustered underneath a patch of land situated between the I-580 and Old U.S. 395, about 1.4 miles from Galena High School and in the same area as the Ormat Steamboat Geothermal Power Plant. But there’s no evidence the swarm is associated with the plant since it is occurring six to seven kilometers below the ground, far deeper than the Ormat plant’s activities.
It’s unclear as to what exact fault system is producing this swarm. Faults in the area produced sizable quakes as recently as 2015. That seismic event, known as the “Thomas Creek Sequence,” produced a series of magnitude 3.0’s that culminated with a magnitude 4.0.
People living in Northern Nevada need to be prepared for the smaller, more commonplace, earthquakes just as much as they’d be prepared for the “big one.”
Is this earthquake swarm in Reno a sign for larger events to come?
