M3.6 Earthquake 15 km NW of Pinnacles, CA — July 9, 2026
2026-07-09 14:49:17 UTC (37 min ago) · approx. 6:49 AM UTC-8 local
Felt by 151 people across surrounding communities.
On July 9, 2026 at 14:49 UTC, a magnitude 3.6 shallow crustal earthquake struck 15 km NW of Pinnacles, CA, at a depth of 12.0 km and coordinates 36.6273°, -121.2695°. The earthquake was reported felt by 151 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.7 (light). This earthquake was detected by 80 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 253, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 4.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 190 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 3.6 earthquake near Pinnacles, CA?
The magnitude 3.6 earthquake that struck 15 km NW of Pinnacles, CA on July 9, 2026 at 14:49 UTC had a depth of 12.0 km. It was felt by 151 people with maximum shaking intensity of MMI 3.7 (light). For context, this was a minor earthquake typically detected only by instruments.
Where did the earthquake occur?
The earthquake epicenter was located at 36.6273°, -121.2695°, which is 15 km NW of Pinnacles, CA. View all earthquakes in California.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.6 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 3.6 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.
