On March 5, 2024 at 20:30 UTC, a magnitude 4.3 shallow crustal earthquake struck 33 km SW of Tocopilla, Chile, at a depth of 33.5 km and coordinates -22.3351°, -70.3886°.
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.
