Felt by 30 people across nearby locations.
On June 8, 2024 at 23:33 UTC, a magnitude 3.3 shallow crustal earthquake struck 17 km SW of Oasis, CA, at a depth of 11.6 km and coordinates 33.3423°, -116.2052°. This earthquake was detected by 106 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 180, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 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.
