M3.5 Earthquake 18 km SSE of Silver Springs, Nevada — April 22, 2026
2026-04-22 17:22:14 UTC (3 hours ago)
Felt by 27 people across nearby locations. Maximum shaking intensity MMI 4.2 (moderate). Aftershock of the M5.7 mainshock.
On April 22, 2026 at 17:22 UTC, a magnitude 3.5 shallow crustal earthquake struck 18 km SSE of Silver Springs, Nevada, at a depth of 4.0 km and coordinates 39.2759°, -119.1148°. The earthquake was reported felt by 27 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.2 (moderate). This earthquake was detected by 12 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 196, placing it among routine seismic activity.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.7 mainshock that occurred 8 days ago 20 km ESE of Silver Springs, Nevada. Since the mainshock, the USGS has recorded 163 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
The epicenter is located in Nevada, a region characterized by Basin and Range extensional tectonics, where normal faulting accommodates east-west crustal stretching at approximately 10 mm per year. The nearest mapped fault system is the Walker Lane fault zone. View all earthquakes in Nevada.

Common Questions
How strong was the magnitude 3.5 earthquake near Silver Springs, Nevada?
The magnitude 3.5 earthquake that struck 18 km SSE of Silver Springs, Nevada on April 22, 2026 at 17:22 UTC had a depth of 4.0 km. It was felt by 27 people with maximum shaking intensity of MMI 4.2 (moderate). For context, this was a minor earthquake typically detected only by instruments.
Where did the earthquake occur?
The earthquake epicenter was located at 39.2759°, -119.1148°, which is 18 km SSE of Silver Springs, Nevada. View all earthquakes in Nevada.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.5 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.7 one earlier?
No. This magnitude 3.5 earthquake is an aftershock of the larger magnitude 5.7 mainshock that occurred earlier 20 km ESE of Silver Springs, Nevada. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
Has Nevada had earthquakes this big before?
The largest recorded earthquake in Nevada was the M7.3 Pleasant Valley earthquake of October 2, 1915. Today's magnitude 3.5 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
