2022-04-08 18:04:08 UTC (2022-04-08) · approx. 10:04 AM UTC-8 local
On April 8, 2022 at 18:04 UTC, a magnitude 2.8 shallow crustal earthquake struck 10km NNW of Cholame, CA, at a depth of 10.3 km and coordinates 35.7982°, -120.3475°.
Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 256 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 53 m — a useful intuition for the size of the slip patch on the fault.
