2025-07-02 22:43:08 UTC (2025-07-02) · approx. 8:43 AM UTC+10 local
On July 2, 2025 at 22:43 UTC, a magnitude 4.4 shallow crustal earthquake struck 226 km E of Kuril’sk, Russia, at a depth of 64.4 km and coordinates 45.5092°, 150.7402°.
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.
