2025-08-10 18:06:37 UTC (2025-08-10) · approx. 1:06 PM UTC-5 local
On August 10, 2025 at 18:06 UTC, a magnitude 4.0 intermediate depth earthquake struck 7 km SSW of María Elena, Chile, at a depth of 70.6 km and coordinates -22.4091°, -69.6874°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
