2021-09-24 19:18:57 UTC (2021-09-24) · approx. 11:18 AM UTC-8 local
On September 24, 2021 at 19:18 UTC, a magnitude 3.0 shallow crustal earthquake struck 60 km ENE of San Vicente, Mexico, at a depth of 24.4 km and coordinates 31.4467°, -115.6297°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
