On December 22, 2024 at 19:03 UTC, a magnitude 3.5 shallow crustal earthquake struck 21 km SSW of Little Lake, CA, at a depth of 2.7 km and coordinates 35.7720°, -118.0117°. The earthquake was reported felt by 17 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.7 (light). This earthquake was detected by 46 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 200, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 3.2 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 170 m — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in California, a region characterized by the San Andreas transform fault system, where the Pacific and North American plates slide past each other at roughly 46 mm per year. The nearest mapped fault system is the San Andreas Fault. View all earthquakes in California.

Common Questions

How strong was the magnitude 3.5 earthquake near Little Lake, CA?

The magnitude 3.5 earthquake that struck 21 km SSW of Little Lake, CA on December 22, 2024 at 19:03 UTC had a depth of 2.7 km. It was felt by 17 people with maximum shaking intensity of MMI 3.7 (light). For context, this was a minor earthquake typically detected only by instruments.

Where did the earthquake occur?

The earthquake epicenter was located at 35.7720°, -118.0117°, which is 21 km SSW of Little Lake, CA. View all earthquakes in California.

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.

Has California had earthquakes this big before?

The largest recorded earthquake in California was the M7.9 Fort Tejon earthquake of January 9, 1857. Today's magnitude 3.5 event is significantly smaller than that historical record.
