M3.3 Earthquake 21 km ESE of Silver Springs, Nevada — April 26, 2026
2026-04-26 07:15:21 UTC (1 hour ago) · approx. 11:15 PM UTC-8 local
On April 26, 2026 at 07:15 UTC, a magnitude 3.3 shallow crustal earthquake struck 21 km ESE of Silver Springs, Nevada, at a depth of 6.4 km and coordinates 39.3490°, -118.9892°. The earthquake was reported felt by 3 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.0 (light).
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 110 m — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.7 mainshock that occurred 12 days ago 20 km ESE of Silver Springs, Nevada. Since the mainshock, the USGS has recorded 173 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 3.3 earthquake near Silver Springs, Nevada?
The magnitude 3.3 earthquake that struck 21 km ESE of Silver Springs, Nevada on April 26, 2026 at 07:15 UTC had a depth of 6.4 km. It was felt by 3 people with maximum shaking intensity of MMI 3.0 (light). For context, this was a minor earthquake typically detected only by instruments.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.3 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 3.3 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.
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.
