On March 17, 2023 at 19:19 UTC, a magnitude 4.3 shallow crustal earthquake struck 51 km NNW of Bah?a de Car?quez, Ecuador, at a depth of 18.6 km and coordinates -0.1877°, -80.6510°.

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.
