South Reno earthquake swarm: 230 quakes and counting

While earthquakes in Northern Nevada are commonplace (The Silver State is the third-most seismically active state in the nation), Smith said he and his colleagues at UNR’s Nevada Seismological Laboratory pay special attention to earthquake swarms.

Swarms of small earthquakes can sometimes act as pseudo warning systems for larger events to come.

Smith said there’s no telling if this swarm will die off or yield something larger.

“But if they do, we want to be on top of it,” he said. “In a way it’s kind of a heads up.”

Two of Reno’s more recent seismic events, a 2013 magnitude 4.4 temblor in Spanish Springs and the 2008 magnitude 4.7 in Mogul/Somersett were both preceded by hundreds of small earthquakes.
