2021-07-11 21:07:22 UTC (2021-07-11) · approx. 7:07 AM UTC+10 local
On July 11, 2021 at 21:07 UTC, a magnitude 4.7 intermediate depth earthquake struck near Kuril Islands, at a depth of 72.9 km and coordinates 46.5653°, 151.6745°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
