2022-09-08 22:15:31 UTC (2022-09-08) · approx. 8:15 AM UTC+10 local
On September 8, 2022 at 22:15 UTC, a magnitude 4.5 intermediate depth earthquake struck near Kuril Islands, at a depth of 148.1 km and coordinates 47.4273°, 152.2430°. This earthquake was detected by 34 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
