On June 15, 2026 at 03:26 UTC, a magnitude 3.2 shallow crustal earthquake struck 10 km NW of Calipatria, CA, at a depth of 6.5 km and coordinates 33.1767°, -115.6010°. The earthquake was reported felt by 6 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.2 (moderate).

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 979 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 99 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 3.2 earthquake near Calipatria, CA?

The magnitude 3.2 earthquake that struck 10 km NW of Calipatria, CA on June 15, 2026 at 03:26 UTC had a depth of 6.5 km. It was felt by 6 people with maximum shaking intensity of MMI 4.2 (moderate). 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 3.2 earthquakes can continue for several days and gradually diminish over time.

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.
