On March 13, 2025 at 20:00 UTC, a magnitude 4.0 intermediate depth earthquake struck 82 km ESE of Ollagüe, Chile, at a depth of 220.0 km and coordinates -21.4876°, -67.5115°.
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.
