Magnitude 4.2 earthquake reported by Nevada Seismological Laboratory; largest of sequence that started five days ago

RENO, Nev. – The Nevada Seismological Laboratory reports a Magnitude 4.2 earthquake located just north of Spanish Springs, Nev. at 5:51 p.m. There have been a few unconfirmed reports of minor damage. This quake is the largest in a sequence in that area that began five days ago and was preceded by a M2.4 at about 5:30 p.m.

There have been several small swarms of earthquakes in the area north of Reno during 2013. The Magnitude 4.2 Spanish Springs earthquake occurred in the same area as a small swarm of earthquakes that took place in October 2012.

“Activity began again in this same location on August 21 leading to today’s felt event,” Ken Smith, associate director of the Nevada Seismological Laboratory at the University of Nevada, Reno, said. “This earthquake has been followed by several aftershocks, which is typical of earthquakes of this size in the northern Nevada region.

“It’s always a possibility, yet just as unlikely, that this event may be a foreshock to a larger event that may occur near the same location, and citizens in the north Reno area should remain on alert for additional ground shaking. How this series of earthquakes will evolve cannot be predicted or forecast.”

The event was felt as far away as the western Sierra foothills and to the east in Fallon, Nevada, with some reports from as far away as Sacramento and Susanville, Calif. It was 8.6 miles below the surface.

A series of small aftershocks between M1.4 and 1.7 have occurred following the 5:51 p.m. earthquake.

The Nevada-Eastern California region has a history of large damaging earthquakes and citizens should always consider earthquake preparedness. Information is available at the Great Nevada Shakeout website, www.shakeout.org/nevada/, or at www.readywashoe.com.

The Nevada Seismological Laboratory, a public service department at the University of Nevada, Reno, is a member of the USGS Advanced National Seismic System (http://www.anss.org) and operates a network of about 150 real-time seismograph stations throughout the region providing earthquake information to Nevada citizens, the USGS, and local and state officials.
