On November 29, 2021 at 20:33 UTC, a magnitude 4.9 intermediate depth earthquake struck 4 km NNW of Trujillo, Colombia, at a depth of 123.1 km and coordinates 4.2503°, -76.3426°.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
