On September 16, 2023 at 13:29 UTC, a magnitude 4.9 intermediate depth earthquake struck 3 km SW of Cepitá, Colombia, at a depth of 157.8 km and coordinates 6.7300°, -72.9926°. This earthquake was detected by 59 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 370, placing it among routine seismic activity.

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.
