On June 17, 2023 at 22:52 UTC, a magnitude 3.5 shallow crustal earthquake struck near Near the coast of Tarapaca, Chile, at a depth of 35.0 km and coordinates -20.5142°, -70.5666°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
