On September 21, 2025 at 20:17 UTC, a magnitude 4.9 shallow crustal earthquake struck 25 km WSW of Abriaquí, Colombia, at a depth of 10.0 km and coordinates 6.5236°, -76.2637°. This earthquake was detected by 64 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 374, 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.
