2023-12-30 23:55:48 UTC (2023-12-30) · approx. 9:55 AM UTC+10 local
On December 30, 2023 at 23:55 UTC, a magnitude 4.4 shallow crustal earthquake struck 108 km SE of Kuril’sk, Russia, at a depth of 35.0 km and coordinates 44.6077°, 148.9343°.
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.
