M3.3 Earthquake 24 km NNE of Yerington, Nevada — December 9, 2024
2024-12-09 23:49:05 UTC (2024-12-09) · approx. 3:49 PM UTC-8 local
Felt by 18 people across nearby locations.
On December 9, 2024 at 23:49 UTC, a magnitude 3.3 shallow crustal earthquake struck 24 km NNE of Yerington, Nevada, at a depth of 6.8 km and coordinates 39.1787°, -119.0205°. The earthquake was reported felt by 18 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 2.9 (weak). This earthquake was detected by 27 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 175, placing it among routine seismic activity.
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 114 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.

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.
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 3.3 event is significantly smaller than that historical record.
