An earthquake swarm that has been striking a corner of the Nevada desert near the Oregon and California border for months has intensified in recent days, prompting new warnings from seismologists. There have been 150 in the last week alone!
About 750 earthquakes, mostly magnitude 2.0 to 3.0, have struck the area about 50 miles southeast of Lakeview, Ore., since the swarm started in July 2014. The temblors have been growing steadily stronger with time. Six earthquakes of magnitude 4.0 or greater have struck the area since last Tuesday.
The swarm is beneath an uninhabited part of the Nevada desert near the Sheldon National Wildlife Refuge, but officials are telling the public, especially the almost 2,300 residents of Lakeview, to develop earthquake plans if they haven’t already. Scientists believe groundwater is slowly percolating along the faults and building up pressure, making movement on the faults much easier.
If you aren’t ready for an earthquake, now might be a good time to start!
