On August 30, 2025 at 21:50 UTC, a magnitude 4.5 intermediate depth earthquake struck 13 km SSW of Piedecuesta, Colombia, at a depth of 147.3 km and coordinates 6.8850°, -73.1159°. This earthquake was detected by 38 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
