2025-10-24 17:05:53 UTC (2025-10-24) · approx. 12:05 AM UTC+7 local
On October 24, 2025 at 17:05 UTC, a magnitude 4.1 shallow crustal earthquake struck 50 km SE of Severobaykal’sk, Russia, at a depth of 10.0 km and coordinates 55.2758°, 109.8148°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
