M3.1 Earthquake in the Puerto Rico region — November 24, 2023
2023-11-24 22:36:54 UTC (2023-11-24) · approx. 6:36 PM UTC-4 local
On November 24, 2023 at 22:36 UTC, a magnitude 3.1 shallow crustal earthquake struck in the Puerto Rico region, at a depth of 28.6 km and coordinates 19.4805°, -65.8867°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 607 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 79 m — a useful intuition for the size of the slip patch on the fault.
