On August 29, 2023 at 21:31 UTC, a magnitude 4.6 shallow crustal earthquake struck 20 km NE of Bahía de Caráquez, Ecuador, at a depth of 40.1 km and coordinates -0.4475°, -80.3221°. This earthquake was detected by 56 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
