M4.9 Earthquake east of the Kuril Islands — January 9, 2022
2022-01-09 23:29:31 UTC (2022-01-09) · approx. 9:29 AM UTC+10 local
On January 9, 2022 at 23:29 UTC, a magnitude 4.9 shallow crustal earthquake struck east of the Kuril Islands, at a depth of 10.0 km and coordinates 47.0908°, 155.6652°.
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.
