2021-09-17 19:36:07 UTC (2021-09-17) · approx. 5:36 AM UTC+10 local
On September 17, 2021 at 19:36 UTC, a magnitude 5.0 intermediate depth earthquake struck near Kuril Islands, at a depth of 88.3 km and coordinates 48.2461°, 153.8981°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
