On September 23, 2022 at 23:44 UTC, a magnitude 4.3 shallow crustal earthquake struck 20 km NE of Santa Elena, Ecuador, at a depth of 32.1 km and coordinates -2.1042°, -80.7245°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
