On June 26, 2026 at 05:41 UTC, a magnitude 2.6 shallow crustal earthquake struck 11 km N of Redwood Valley, CA, at a depth of 7.0 km and coordinates 39.3660°, -123.2272°.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 124 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 38 m — a useful intuition for the size of the slip patch on the fault.

This earthquake is part of an ongoing aftershock sequence following the magnitude 5.6 mainshock that occurred 1 day ago 11 km N of Redwood Valley, CA. Since the mainshock, the USGS has recorded 18 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions

How strong was the magnitude 2.6 earthquake near Redwood Valley, CA?

The magnitude 2.6 earthquake that struck 11 km N of Redwood Valley, CA on June 26, 2026 at 05:41 UTC had a depth of 7.0 km. For context, this was a minor earthquake typically detected only by instruments.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 2.6 earthquakes can continue for several days and gradually diminish over time.

Is this the same earthquake as the M5.6 one earlier?

No. This magnitude 2.6 earthquake is an aftershock of the larger magnitude 5.6 mainshock that occurred earlier 11 km N of Redwood Valley, CA. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

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.
