On October 13, 2026 at 01:44 UTC, a magnitude 4.0 shallow crustal earthquake struck 62 km NW of Tomé, Chile, at a depth of 25.6 km and coordinates -36.1819°, -73.4058°.
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.
