On August 18, 2023 at 17:48 UTC, a magnitude 4.0 intermediate depth earthquake struck 25 km SSE of Camiña, Chile, at a depth of 108.6 km and coordinates -19.5234°, -69.3192°.
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.
