On August 14, 2026 at 12:31 UTC, a magnitude 2.5 shallow crustal earthquake struck 12 km SSW of Lompoc, CA, at a depth of 6.2 km and coordinates 34.5378°, -120.5000°. This earthquake was detected by 33 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 102, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 94.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 34 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 2.5 earthquake near Lompoc, CA?

The magnitude 2.5 earthquake that struck 12 km SSW of Lompoc, CA on August 14, 2026 at 12:31 UTC had a depth of 6.2 km. For context, this was a minor earthquake typically detected only by instruments.

Where did the earthquake occur?

The earthquake epicenter was located at 34.5378°, -120.5000°, which is 12 km SSW of Lompoc, CA. View all earthquakes in California.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 2.5 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 2.5 event is significantly smaller than that historical record.
