On March 24, 2021 at 21:53 UTC, a magnitude 4.4 intermediate depth earthquake struck 41 km SSW of Boca Suno, Ecuador, at a depth of 221.7 km and coordinates -1.0290°, -77.3166°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
