2026-03-24 19:21:43 UTC (2026-03-24) · approx. 5:21 AM UTC+10 local
On March 24, 2026 at 19:21 UTC, a magnitude 4.2 shallow crustal earthquake struck near Kuril Islands, at a depth of 40.4 km and coordinates 46.8891°, 152.9888°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
