On May 19, 2025 at 22:28 UTC, a magnitude 4.3 intermediate depth earthquake struck 62 km NE of Taltal, Chile, at a depth of 74.9 km and coordinates -24.9691°, -70.0925°.
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.
