2023-05-17 22:34:23 UTC (2023-05-17) · approx. 8:34 AM UTC+10 local
On May 17, 2023 at 22:34 UTC, a magnitude 4.3 intermediate depth earthquake struck near Kuril Islands, at a depth of 202.3 km and coordinates 47.1764°, 150.9051°.
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.
