2023-10-06 18:54:59 UTC (2023-10-06) · approx. 4:54 AM UTC+10 local
On October 6, 2023 at 18:54 UTC, a magnitude 4.4 shallow crustal earthquake struck near Kuril Islands, at a depth of 31.6 km and coordinates 47.2251°, 153.8002°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
