2023-04-26 22:27:47 UTC (2023-04-26) · approx. 8:27 AM UTC+10 local
On April 26, 2023 at 22:27 UTC, a magnitude 4.3 intermediate depth earthquake struck near Kuril Islands, at a depth of 75.0 km and coordinates 44.4781°, 148.1011°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
