On June 23, 2020 at 20:19 UTC, a magnitude 3.8 shallow crustal earthquake struck 50 km WNW of La Ligua, Chile, at a depth of 35.4 km and coordinates -32.2594°, -71.7159°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
