M4.9 Earthquake east of the Kuril Islands — February 11, 2026
2026-02-11 16:35:06 UTC (2026-02-11) · approx. 2:35 AM UTC+10 local
On February 11, 2026 at 16:35 UTC, a magnitude 4.9 shallow crustal earthquake struck east of the Kuril Islands, at a depth of 10.0 km and coordinates 44.1673°, 151.8302°. This earthquake was detected by 98 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
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.
