On June 30, 2022 at 18:16 UTC, a magnitude 3.1 intermediate depth earthquake struck 4 km SW of Mayagüez, Puerto Rico, at a depth of 102.5 km and coordinates 18.1758°, -67.1697°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 629 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 80 m — a useful intuition for the size of the slip patch on the fault.
