2022-10-10 23:34:36 UTC (2022-10-10) · approx. 7:34 PM UTC-4 local
On October 10, 2022 at 23:34 UTC, a magnitude 3.0 intermediate depth earthquake struck 6 km WNW of Mayagüez, Puerto Rico, at a depth of 109.9 km and coordinates 18.2150°, -67.1983°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
