On October 19, 2026 at 05:18 UTC, a magnitude 4.9 shallow crustal earthquake struck 68 km WSW of San Juan del Sur, Nicaragua, at a depth of 44.0 km and coordinates 11.1229°, -86.4815°. This earthquake was detected by 108 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
