2023-10-06 19:02:21 UTC (2023-10-06) · approx. 5:02 AM UTC+10 local
On October 6, 2023 at 19:02 UTC, a magnitude 4.6 shallow crustal earthquake struck near Kuril Islands, at a depth of 31.0 km and coordinates 47.2147°, 154.0209°. This earthquake was detected by 118 seismic stations with good 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.
