2023-06-23 20:43:48 UTC (2023-06-23) · approx. 3:43 PM UTC-5 local
On June 23, 2023 at 20:43 UTC, a magnitude 4.0 intermediate depth earthquake struck 102 km ENE of Taltal, Chile, at a depth of 88.0 km and coordinates -24.9065°, -69.6300°.
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.
