2023-11-27 20:20:26 UTC (2023-11-27) · approx. 6:20 AM UTC+10 local
On November 27, 2023 at 20:20 UTC, a magnitude 4.6 intermediate depth earthquake struck near Kuril Islands, at a depth of 141.0 km and coordinates 47.1564°, 151.7359°. This earthquake was detected by 96 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
