2025-03-12 17:52:51 UTC (2025-03-12) · approx. 9:52 AM UTC-8 local
On March 12, 2025 at 17:52 UTC, a magnitude 2.7 shallow crustal earthquake struck 10 km NW of The Geysers, CA, at a depth of 1.9 km and coordinates 38.8250°, -122.8513°.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 163 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 43 m — a useful intuition for the size of the slip patch on the fault.
