On May 21, 2023 at 19:19 UTC, a magnitude 4.2 intermediate depth earthquake struck 5 km WSW of Güepsa, Colombia, at a depth of 129.6 km and coordinates 6.0107°, -73.6200°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
