Earthquake swarm rattles Nevada where ground has been ripping apart

A continuing earthquake swarm in western Nevada has persisted for a third week near Silver Springs, about 40 miles east of Reno.
The US Geological Survey reports more than 200 quakes since April 20, including a magnitude 5.2 event on May 1 felt across Nevada and California.
Scientists attribute the activity to crustal stretching in the Basin and Range Province and Walker Lane seismic zone.
Most tremors have been under magnitude 2.0, but three events over the last three weeks exceeded 4.0.
Most activity centers near Silver Springs, with the Lahontan Reservoir also in the swarm zone.
No injuries have been reported amid the ongoing quakes, though residents felt strong shaking and some property damage.
Seismologists say aftershocks can occur after larger quakes, with ongoing activity possible in coming days or weeks.
Experts caution human activity, such as geothermal or mining, can sometimes trigger earthquakes, though most Nevada quakes are natural.
Residents say the swarm area has been the focus of ongoing monitoring by USGS and local authorities.
