On February 29, 2024 at 10:28 UTC, a magnitude 5.2 shallow crustal earthquake struck 251 km W of Crescent City, California, at a depth of 10.0 km and coordinates 41.3681°, -127.1671°. This earthquake was detected by 141 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 417, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — 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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.2 earthquakes can continue for days to weeks 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 5.2 event is significantly smaller than that historical record.
