2025-02-02 15:00:58 UTC (2025-02-02) · approx. 10:00 AM UTC-5 local
On February 2, 2025 at 15:00 UTC, a magnitude 4.4 shallow crustal earthquake struck 46 km WSW of San Antonio, Chile, at a depth of 10.0 km and coordinates -33.8155°, -72.0293°.
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.
