Another 4.7 magnitude earthquake hit northwest Nevada, tying the largest in a year-long swarm recorded at the Sheldon National Wildlife Refuge near the Oregon border.
The University of Nevada’s Reno Nevada Seismological Laboratory said the 4.7 magnitude earthquake hit the area about 6:55 a.m. Monday.
At least five aftershocks at magnitude 2 or greater have been recorded within the three hours following.
It marks the second 4.7 magnitude earthquake in the wildlife refuge’s year-long swarm, which so far remains the height of the activity.
A previous one was recorded on Nov. 6 as the largest one to hit since the thousands of earthquakes started in July 2014.
Seismologists said in August that a flare-up since mid-July had brought the total to more than 5,600 earthquakes.
