On August 3, 2026 at 06:56 UTC, a magnitude 4.0 intermediate depth earthquake struck 56 km E of La Tirana, Chile, at a depth of 90.5 km and coordinates -20.2891°, -69.1187°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
