On February 14, 2021 at 19:46 UTC, a magnitude 5.4 shallow crustal earthquake struck near off the coast of Ecuador, at a depth of 21.3 km and coordinates 1.0418°, -85.2104°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected.
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
