2025-02-12 15:59:56 UTC (2025-02-12) · approx. 1:59 AM UTC+10 local
On February 12, 2025 at 15:59 UTC, a magnitude 4.2 shallow crustal earthquake struck 113 km SE of Kuril’sk, Russia, at a depth of 45.7 km and coordinates 44.4603°, 148.8331°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
