On July 26, 2026 at 10:04 UTC, a magnitude 4.2 shallow crustal earthquake struck 41 km SSW of Ocós, Guatemala, at a depth of 35.0 km and coordinates 14.1489°, -92.3106°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
