On June 19, 2023 at 05:19 UTC, a magnitude 5.3 shallow crustal earthquake struck 222 km SSW of Río Grande, Panama, at a depth of 10.0 km and coordinates 5.9842°, -82.3534°. This earthquake was detected by 267 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
