2021-12-02 13:52:42 UTC (2021-12-02) · approx. 8:52 AM UTC-5 local
On December 2, 2021 at 13:52 UTC, a magnitude 4.8 shallow crustal earthquake struck 12 km SE of Riosucio, Colombia, at a depth of 35.0 km and coordinates 7.3528°, -77.0462°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
