On September 1, 2022 at 04:03 UTC, a magnitude 4.7 shallow crustal earthquake struck 46 km S of Champerico, Guatemala, at a depth of 35.0 km and coordinates 13.8733°, -91.9335°. This earthquake was detected by 65 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
