2021-04-19 04:10:05 UTC (2021-04-19) · approx. 10:10 PM UTC-6 local
On April 19, 2021 at 04:10 UTC, a magnitude 5.3 shallow crustal earthquake struck near off the coast of Ecuador, at a depth of 10.0 km and coordinates 1.5464°, -85.3063°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
