On September 24, 2024 at 22:18 UTC, a magnitude 4.3 shallow crustal earthquake struck 80 km WNW of Lebu, Chile, at a depth of 10.0 km and coordinates -37.2391°, -74.4386°.
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.
