On February 12, 2024 at 08:36 UTC, a magnitude 4.8 shallow crustal earthquake struck 3 km NNW of El Centro, CA, at a depth of 17.9 km and coordinates 32.8135°, -115.5735°. The earthquake was reported felt by 2,056 peopleacross a wide area, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.8 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 71 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 926, making it one of the more significant events of the week. The nearest populated place is Imperial (population 14,758).

Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 247 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.3 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.

Common Questions

How strong was the magnitude 4.8 earthquake near El Centro, CA?

The magnitude 4.8 earthquake that struck 3 km NNW of El Centro, CA on February 12, 2024 at 08:36 UTC had a depth of 17.9 km. It was felt by 2,056 people with maximum shaking intensity of MMI 5.8 (strong). For context, this was a light earthquake commonly felt near the epicenter.

Where did the earthquake occur?

The earthquake epicenter was located at 32.8135°, -115.5735°, which is 3 km NNW of El Centro, CA. The nearest populated place is Imperial (population 14,758). View all earthquakes in California.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.8 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 4.8 event is significantly smaller than that historical record.
