On October 31, 2024 at 18:14 UTC, a magnitude 3.5 shallow crustal earthquake struck 29 km SE of Baláo, Ecuador, at a depth of 10.0 km and coordinates -3.0890°, -79.6181°.

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
