On August 8, 2026 at 15:33 UTC, a magnitude 4.5 shallow crustal earthquake struck near Kuril Islands, at a depth of 34.9 km and coordinates 46.7745°, 153.0277°. This earthquake was detected by 70 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.
