2024-06-25 19:40:51 UTC (2024-06-25) · approx. 2:40 PM UTC-5 local
On June 25, 2024 at 19:40 UTC, a magnitude 3.2 shallow crustal earthquake struck 104 km NW of San Antonio, Puerto Rico, at a depth of 29.0 km and coordinates 19.2668°, -67.6630°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 1.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 100 m — a useful intuition for the size of the slip patch on the fault.
