On December 7, 2020 at 22:40 UTC, a magnitude 4.0 intermediate depth earthquake struck 13 km SSW of Piedecuesta, Colombia, at a depth of 144.9 km and coordinates 6.8728°, -73.0950°.

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
