On January 17, 2024 at 21:21 UTC, a magnitude 4.4 intermediate depth earthquake struck 78 km SE of La Tirana, Chile, at a depth of 109.3 km and coordinates -20.7853°, -69.0696°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
