On September 3, 2022 at 02:16 UTC, a magnitude 4.9 shallow crustal earthquake struck near Kuril Islands, at a depth of 46.7 km and coordinates 47.6247°, 154.1404°. This earthquake was detected by 78 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.
