On May 11, 2026 at 11:04 UTC, a magnitude 2.9 shallow crustal earthquake struck 22 km SSE of Redway, CA, at a depth of 3.0 km and coordinates 39.9455°, -123.7123°. This earthquake was detected by 40 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 134, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 362 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 62 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 2.9 earthquake near Redway, CA?

The magnitude 2.9 earthquake that struck 22 km SSE of Redway, CA on May 11, 2026 at 11:04 UTC had a depth of 3.0 km. For context, this was a minor earthquake typically detected only by instruments.

Where did the earthquake occur?

The earthquake epicenter was located at 39.9455°, -123.7123°, which is 22 km SSE of Redway, CA. View all earthquakes in California.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 2.9 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 2.9 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. For detailed guidance, see our earthquake safety guide and emergency planning resources.
