On November 28, 2021 at 09:42 UTC, a magnitude 4.7 shallow crustal earthquake struck 23 km ENE of Riosucio, Colombia, at a depth of 27.7 km and coordinates 7.5242°, -76.9244°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
