M4.9 Earthquake near Kuril Islands — December 10, 2021
2021-12-10 11:55:29 UTC (2021-12-10) · approx. 9:55 PM UTC+10 local
On December 10, 2021 at 11:55 UTC, a magnitude 4.9 shallow crustal earthquake struck near Kuril Islands, at a depth of 51.3 km and coordinates 47.2486°, 153.2429°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
