M4.0 Earthquake 20 km ESE of Silver Springs, Nevada — June 12, 2026
2026-06-12 12:12:29 UTC (2026-06-12) · approx. 4:12 AM UTC-8 local
Felt by 137 people across surrounding communities. Maximum shaking intensity MMI 4.2 (moderate).
On June 12, 2026 at 12:12 UTC, a magnitude 4.0 shallow crustal earthquake struck 20 km ESE of Silver Springs, Nevada, at a depth of 2.0 km and coordinates 39.3464°, -118.9997°. The earthquake was reported felt by 137 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.2 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 24 seismic stations with good location accuracy and was assigned a USGS significance rating of 302, placing it among routine seismic activity. The nearest populated place is Fallon (population 9,068).
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 16 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 358 m — a useful intuition for the size of the slip patch on the fault.
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.

What the Shaking Felt Like
At MMI 4.2 (moderate), people in the most strongly affected areas would have experienced: Mild shaking, similar to a passing truck. Hanging objects swing. Glasses and dishes may rattle. Not commonly felt outdoors.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.0 earthquakes can continue for several days and gradually diminish over time.
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 4.0 event is significantly smaller than that historical record.
