On September 3, 2025 at 14:56 UTC, a magnitude 5.3 intermediate depth earthquake struck 16 km E of Puyo, Ecuador, at a depth of 161.8 km and coordinates -1.5015°, -77.8560°. This earthquake was detected by 377 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 434, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
