On September 6, 2026 at 06:09 UTC, a magnitude 4.3 shallow crustal earthquake struck 10 km SW of Lautaro, Chile, at a depth of 64.6 km and coordinates -38.6000°, -72.5249°.
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.
