2022-01-23 18:28:41 UTC (2022-01-23) · approx. 1:28 PM UTC-5 local
On January 23, 2022 at 18:28 UTC, a magnitude 4.4 intermediate depth earthquake struck 161 km NNE of Calama, Chile, at a depth of 148.3 km and coordinates -21.0407°, -68.5580°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
