2022-03-28 21:52:10 UTC (2022-03-28) · approx. 5:52 PM UTC-4 local
On March 28, 2022 at 21:52 UTC, a magnitude 3.2 shallow crustal earthquake struck 18 km SE of Esperanza, Puerto Rico, at a depth of 7.2 km and coordinates 17.9743°, -65.3523°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
