2025-11-18 19:58:02 UTC (2025-11-18) · approx. 2:58 PM UTC-5 local
On November 18, 2025 at 19:58 UTC, a magnitude 4.1 shallow crustal earthquake struck 92 km NNE of Taltal, Chile, at a depth of 56.4 km and coordinates -24.6314°, -70.1341°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
