2021-12-12 23:50:03 UTC (2021-12-12) · approx. 9:50 AM UTC+10 local
On December 12, 2021 at 23:50 UTC, a magnitude 4.4 deep-focus earthquake struck near Sea of Okhotsk, at a depth of 539.8 km and coordinates 53.3714°, 153.1855°.
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.
