2025-05-05 16:58:47 UTC (2025-05-05) · approx. 11:58 AM UTC-5 local
On May 5, 2025 at 16:58 UTC, a magnitude 3.9 shallow crustal earthquake struck 45 km NNW of Huara, Chile, at a depth of 60.4 km and coordinates -19.6387°, -69.9926°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
