On June 14, 2021 at 21:05 UTC, a magnitude 4.9 shallow crustal earthquake struck 29 km SW of Montecristi, Ecuador, at a depth of 10.0 km and coordinates -1.1920°, -80.8752°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
