Felt by 57 people across nearby locations.
On August 18, 2023 at 01:15 UTC, a magnitude 5.0 shallow crustal earthquake struck 10 km N of Cumaral, Colombia, at a depth of 10.0 km and coordinates 4.3633°, -73.4850°. This earthquake was detected by 80 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 415, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
