On November 5, 2023 at 15:48 UTC, a magnitude 3.3 shallow crustal earthquake struck 0 km E of Hospital, Chile, at a depth of 49.7 km and coordinates -20.2143°, -70.1323°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
