On December 14, 2021 at 21:22 UTC, a magnitude 4.5 intermediate depth earthquake struck 7 km NNE of Guanagazapa, Guatemala, at a depth of 191.2 km and coordinates 14.2868°, -90.6120°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
