On October 6, 2024 at 20:40 UTC, a magnitude 3.9 shallow crustal earthquake struck 14 km ESE of Alto Hospicio, Chile, at a depth of 56.5 km and coordinates -20.3142°, -69.9777°.

Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
