Nevada has experienced four earthquakes since 8am ET, with the strongest reaching a 4.0 magnitude.
The swarm hit Valmy, which is about 200 miles southwest of Reno, on Monday.
The US Geological Survey (USGS) predicts a 27 percent chance of another 3.0 magnitude or higher quake hitting within the next week.
There is also a five percent chance of a 4.0 magnitude or higher.
The 4.0 magnitude hit at 12:28pm ET, about 50 miles northwest of Carlin, 71 miles east and northeast of Winnemucca and 32 miles north of Battle Mountain, according to the Nevada Seismological Laboratory at the University of Reno.
Nevada is the nation's third-most seismically active state, ranking after California and Alaska.
Valmy sits within a region of active fault lines, including the Fairview Peak-Dixie Valley Fault Scarps and the Central Nevada Seismic Belt.
The small town is also along the Pleasant Valley fault that is capable of producing a quake up to a 7.7 magnitude.
The USGS detected the first quake, a 3.4 magnitude, at 8:03am ET.
A second 2.6 magnitude hit at 12:24pm and the 4.0 magnitude was detected just four minutes later.
And the fourth earthquake, a 2.9 magnitude, was reported at 1:29pm ET.
While a swarm like this would be felt by hundreds of people, the epicenter is in the Great Basin that is sparsely populated.
USGS received only three reports of shaking in the area. However, those individuals said they felt 'strong shaking.'
Since this area is part of the Basin, it experiences active crustal stretching, fault movements and occasional deep fluid activity.
There is also mining in the region that can trigger quakes.
Valmy is home to the Twin Creeks Mine and Turquoise Ridge Mine, both of which are substantial gold-producing sites operated by major mining companies.
These operations involve extensive excavation, blasting, and material processing, which can alter the stress distribution in the Earth's crust, potentially inducing seismic events or earthquake swarms in the surrounding area.
Nevada's Area 51 was recently hit by a 2.8 magnitude earthquake in February.
The USGS said the quake struck 32 miles southeast of Beatty that sits about 60 miles from the mysterious military facility.
A 5.7 magnitude earthquake shook northern Nevada on December 9, 2024.
It was the largest quake since May 15, 2020, when a 6.5 magnitude earthquake struck the Monte Cristo Range.
Nevada experiences thousands of microearthquakes each year, according to Shakeout.
'Earthquakes in Western Nevada are caused by the extension that is pulling Nevada apart and wrenching created as the Sierra Nevada is pulled to the north because it is caught up in the Pacific-North America plate motion,' the site explains.
