2023-01-11 20:20:12 UTC (2023-01-11) · approx. 3:20 PM UTC-5 local
On January 11, 2023 at 20:20 UTC, a magnitude 4.0 shallow crustal earthquake struck 53 km W of Taltal, Chile, at a depth of 35.0 km and coordinates -25.4853°, -71.0059°.
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.
