2023-05-31 21:12:22 UTC (2023-05-31) · approx. 1:12 PM UTC-8 local
On May 31, 2023 at 21:12 UTC, a magnitude 3.1 shallow crustal earthquake struck 32km E of Maneadero, B.C., MX, at a depth of 5.4 km and coordinates 31.7395°, -116.2335°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 629 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 80 m — a useful intuition for the size of the slip patch on the fault.
