2025-01-08 20:28:10 UTC (2025-01-08) · approx. 7:28 AM UTC+11 local
On January 8, 2025 at 20:28 UTC, a magnitude 3.9 intermediate depth earthquake struck 71 km S of Klyuchi, Russia, at a depth of 111.9 km and coordinates 55.6774°, 160.9238°.
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.
