On April 26, 2026 at 10:27 UTC, a magnitude 2.7 shallow crustal earthquake struck 16 km E of Seven Trees, CA, at a depth of 6.7 km and coordinates 37.2883°, -121.6593°. This earthquake was detected by 90 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 124, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 169 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 44 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 2.7 earthquake near Seven Trees, CA?

The magnitude 2.7 earthquake that struck 16 km E of Seven Trees, CA on April 26, 2026 at 10:27 UTC had a depth of 6.7 km. For context, this was a minor earthquake typically detected only by instruments.

The earthquake epicenter was located at 37.2883°, -121.6593°, which is 16 km E of Seven Trees, CA. View all earthquakes in California.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 2.7 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 2.7 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.
