2022-07-02 19:51:51 UTC (2022-07-02) · approx. 2:51 PM UTC-5 local
On July 2, 2022 at 19:51 UTC, a magnitude 3.8 shallow crustal earthquake struck 46 km WNW of Tocopilla, Chile, at a depth of 20.2 km and coordinates -21.9373°, -70.6179°.
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.
