On August 4, 2024 at 23:42 UTC, a magnitude 4.4 shallow crustal earthquake struck 65 km E of Macas, Ecuador, at a depth of 39.9 km and coordinates -2.3806°, -77.5310°.

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.
