Earthquake activity in northwest Nevada over the past week has been more than in previous months combined, says the Nevada Seismological Laboratory.
In the past week, there has an increase in both the strength and the number of earthquakes occurring as part of an ongoing earthquake swarm in northwestern Nevada. The swarm began five months ago, on July 12. As of November 12, 2014, there have been 101 earthquakes larger than magnitude 3.0, with the largest earthquake a magnitude 4.7, according to the Nevada Seismological Laboratory (NSL). A magnitude-4.1 earthquake struck the area yesterday morning (November 12, 2014) at 6:42 a.m. local time. Last night, at 22:36 p.m. local time, a magnitude-4.6 earthquake struck. In all, since July, nine earthquakes in this area have measured larger than magnitude 4.0. NSL said in aNovember 12 article on its website:
The Nevada Seismological Laboratory is in contact with local residents in hopes of deploying instruments near the swarm in the upcoming week … Residents of northwest Nevada have expressed an eagerness to help as they are feeling the daily barrage of M3 and M4 earthquakes.
The swarm is centered about 40 miles southeast of Lakeview, Oregon. It’s centered on a very small area, only about 7 miles long and about 2 miles at its widest point. It’s a sparsely populated area, a plain of dry alkali lakebeds. The Sheldon National Wildlife Refuge and the Summit Lake Indian Reservation are to the east. The Black Rock Desert is to the south.
People want to know if the ongoing earthquake swarm in this region might indicate a large quake to come. Since earthquakes cannot be predicted, there’s no real answer to that question. All experts can do is point to similar events in the past.
Nevada’s 2014 earthquake swarm compares with a swarm in and around Adel, Oregon in 1968. The Oregon swarm also lasted several months and caused moderate damage; it included three events of approximately magnitude 5.
Another comparison is the 2008 Mogul-Somersett swarm near Reno, Nevada. AP reported:
