On August 31, 2026 at 21:30 UTC, a magnitude 4.3 shallow crustal earthquake struck 50 km SW of Taltal, Chile, at a depth of 27.0 km and coordinates -25.7630°, -70.7989°.
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.
