2022-09-28 23:06:37 UTC (2022-09-28) · approx. 7:06 PM UTC-4 local
On September 28, 2022 at 23:06 UTC, a magnitude 3.0 shallow crustal earthquake struck 5 km SSW of Potala Pastillo, Puerto Rico, at a depth of 9.4 km and coordinates 17.9463°, -66.5217°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 511 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 73 m — a useful intuition for the size of the slip patch on the fault.
