2026-07-28 06:05:52 UTC (8 hours ago) · approx. 1:05 AM UTC-5 local
On July 28, 2026 at 06:05 UTC, a magnitude 3.2 intermediate depth earthquake struck 13 km SSE of La Tirana, Chile, at a depth of 71.8 km and coordinates -20.3865°, -70.0661°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
