On February 18, 2021 at 10:51 UTC, a magnitude 5.2 intermediate depth earthquake struck 14 km SSW of Yantzaza, Ecuador, at a depth of 99.9 km and coordinates -3.9543°, -78.8053°.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
