On March 15, 2026 at 05:00 UTC, a magnitude 5.3 shallow crustal earthquake struck 64 km SSW of Intipucá, El Salvador, at a depth of 64.8 km and coordinates 12.6399°, -88.2233°. This earthquake was detected by 114 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 435, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
