On March 11, 2023 at 22:56 UTC, a magnitude 4.4 shallow crustal earthquake struck 37 km S of Iztapa, Guatemala, at a depth of 60.8 km and coordinates 13.5981°, -90.6883°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
