2026-07-20 20:53:40 UTC (1 day ago) · approx. 6:53 AM UTC+10 local
On July 20, 2026 at 20:53 UTC, a magnitude 4.4 shallow crustal earthquake struck near Kuril Islands, at a depth of 50.8 km and coordinates 47.0895°, 152.6471°.
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.
