2024-12-07 20:56:05 UTC (2024-12-07) · approx. 4:56 PM UTC-4 local
On December 7, 2024 at 20:56 UTC, a magnitude 3.0 shallow crustal earthquake struck 21 km NW of Rincón, Puerto Rico, at a depth of 13.0 km and coordinates 18.4537°, -67.4172°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 567 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 77 m — a useful intuition for the size of the slip patch on the fault.
