On March 21, 2024 at 16:09 UTC, a magnitude 3.9 shallow crustal earthquake struck 74 km SW of Taltal, Chile, at a depth of 11.1 km and coordinates -25.8185°, -71.0677°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
