18 Moderate Quakes Strike Northern Nevada In Less Than 24 Hours
(CBS SF) -- A swarm of earthquakes ranging from magnitude 2.7 to 4.5 struck northern Nevada near the borders of Oregon and California between Wednesday morning and Thursday morning. The tremors came just after a preliminary magnitude 4.9 earthquake shook the same area.
A USGS readout of the seismic activity shows the cluster of earthquakes striking near the Calcutta Lake area between 9 a.m. Wednesday and 8 a.m. Thursday.
According to the U.S. Geological Survey's automated seismograph alert network, the largest earthquake struck at 12:34 a.m. Pacific time near the Sheldon National Wildlife Refuge. The remote area is located about 40 miles southeast of Lakeview, Oregon, 117 miles northeast of Susanville, and nearly 200 miles north of Carson City, Nevada .
The area has recently seen a spike in earthquake activity.
The quake struck near the surface at a depth of 3.3 miles, which can feel much stronger than their actual reported magnitude.
