Since Sunday, the US Geological Survey has detected 19 minor earthquakes near Silver Springs, roughly 40 miles east of Reno.
Five of those earthquakes struck the area on Monday, with the largest ones registering at 2.5 in magnitude.
However, since April 20, monitoring stations have picked up more than 200 earthquakes, all centered in the same area of Nevada, including a significant magnitude 5.2 quake on May 1 which was felt across the state and in California.
The epicenter of this month-long swarm lies in the Basin and Range Province, a vast region stretching across much of the western US.
