On April 10, 2022 at 22:10 UTC, a magnitude 4.0 intermediate depth earthquake struck 106 km E of Iquique, Chile, at a depth of 113.9 km and coordinates -20.1212°, -69.1320°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
