2025-09-25 23:19:06 UTC (2025-09-25) · approx. 9:19 AM UTC+10 local
On September 25, 2025 at 23:19 UTC, a magnitude 4.4 intermediate depth earthquake struck near Kuril Islands, at a depth of 86.3 km and coordinates 46.8042°, 152.2500°.
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.
