On September 13, 2026 at 17:55 UTC, a magnitude 4.3 intermediate depth earthquake struck 12 km S of Piedecuesta, Colombia, at a depth of 151.9 km and coordinates 6.8723°, -73.0435°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
