On November 15, 2026 at 04:38 UTC, a magnitude 4.3 intermediate depth earthquake struck 75 km SSE of San Pedro de Atacama, Chile, at a depth of 151.7 km and coordinates -23.5305°, -67.9040°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
