2026-09-22 22:12:26 UTC (5 hours ago) · approx. 5:12 PM UTC-5 local
On September 22, 2026 at 22:12 UTC, a magnitude 4.4 shallow crustal earthquake struck 20 km WSW of Roncesvalles, Colombia, at a depth of 10.0 km and coordinates 3.9480°, -75.7814°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
