A secluded area of Nevada that was rocked by earthquake swarms this summer has seen more extreme events in recent days, bumping up the chances of a large earthquake, the Huffington Post reported on Sunday.
The state's northwest border is the epicenter of the earthquakes, about 40 miles southeast of Oregon. Scientists began picking them up on July 12, according to the Nevada Seismological Laboratory.
The laboratory has logged a total of roughly 550 earthquake events coming in at about a 2.0 magnitude or higher. Three magnitude 4.0 or higher seismic activity quakes have happened since Oct. 30.
A 4.6 magnitude earthquake also shook the area on Tuesday.
The laboratory added that the recent earthquake swarm has mimicked two swarms in the past that led to serious earthquakes, CNN reported.
In Adel, Oregon in 1968, a magnitude 5 earthquake was produced after many months of swarms.
"The Adel swarm caused moderate damage," the NSL said.
A 2008 swarm in Reno, Nevada also caused a magnitude 5 earthquake that damaged property in the city.
Despite how it may sound, Nevada's current swarms go undetected by people walking around on the street. The earthquakes have been happening in rural areas, with towns having only about 2,500 residents.
