On August 15, 2026 at 22:45 UTC, a magnitude 4.4 shallow crustal earthquake struck 83 km SSW of Puerto San José, Guatemala, at a depth of 10.0 km and coordinates 13.1890°, -90.9840°.

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.
