On September 26, 2026 at 06:38 UTC, a magnitude 4.6 shallow crustal earthquake struck 25 km W of Roncesvalles, Colombia, at a depth of 10.0 km and coordinates 4.0180°, -75.8315°. This earthquake was detected by 65 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
