On July 11, 2026 at 01:14 UTC, a magnitude 4.4 shallow crustal earthquake struck 11 km N of Covelo, CA, at a depth of 10.7 km and coordinates 39.8867°, -123.2300°. The earthquake was reported felt by 43 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.4 (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 79 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 319, placing it among routine seismic activity. The nearest populated place is Covelo (population 1,317).

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 64 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 676 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 4.4 earthquake near Covelo, CA?

The magnitude 4.4 earthquake that struck 11 km N of Covelo, CA on July 11, 2026 at 01:14 UTC had a depth of 10.7 km. It was felt by 43 people with maximum shaking intensity of MMI 4.4 (moderate). For context, this was a light earthquake commonly felt near the epicenter.

Where did the earthquake occur?

The earthquake epicenter was located at 39.8867°, -123.2300°, which is 11 km N of Covelo, CA. The nearest populated place is Covelo (population 1,317). View all earthquakes in California.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.4 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 4.4 event is significantly smaller than that historical record.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks.
