2021-04-15 16:53:26 UTC (2021-04-15) · approx. 11:53 AM UTC-5 local
On April 15, 2021 at 16:53 UTC, a magnitude 3.2 shallow crustal earthquake struck near Mona Passage, at a depth of 69.0 km and coordinates 18.9193°, -68.7221°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 888 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 94 m — a useful intuition for the size of the slip patch on the fault.
