2024-03-21 17:46:39 UTC (2024-03-21) · approx. 9:46 AM UTC-8 local
On March 21, 2024 at 17:46 UTC, a magnitude 3.1 shallow crustal earthquake struck 73 km S of Maneadero, B.C., MX, at a depth of 11.6 km and coordinates 31.0608°, -116.6415°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
