2025-06-03 22:09:47 UTC (2025-06-03) · approx. 5:09 PM UTC-5 local
On June 3, 2025 at 22:09 UTC, a magnitude 3.9 shallow crustal earthquake struck 74 km NNW of Tocopilla, Chile, at a depth of 27.6 km and coordinates -21.4351°, -70.3704°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
