2025-05-18 14:42:39 UTC (2025-05-18) · approx. 8:42 AM UTC-6 local
On May 18, 2025 at 14:42 UTC, a magnitude 4.4 shallow crustal earthquake struck 102 km WSW of San Juan del Sur, Nicaragua, at a depth of 10.0 km and coordinates 10.8836°, -86.7301°.
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.
