On November 3, 2026 at 09:13 UTC, a magnitude 5.4 shallow crustal earthquake struck 24 km NNW of Rioblanco, Colombia, at a depth of 10.0 km and coordinates 3.7386°, -75.7198°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 79 seismic stations with good location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity. The nearest populated place is Chaparral (population 47,397).

Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
