2026-08-26 10:59:03 UTC (1 hour ago) · approx. 5:59 AM UTC-5 local
On August 26, 2026 at 10:59 UTC, a magnitude 4.3 intermediate depth earthquake struck 75 km ENE of Diego de Almagro, Chile, at a depth of 101.1 km and coordinates -26.1601°, -69.3386°.
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.
