On February 5, 2025 at 23:08 UTC, a magnitude 4.3 intermediate depth earthquake struck 46 km NE of Calama, Chile, at a depth of 129.9 km and coordinates -22.1244°, -68.6522°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
