2024-10-01 22:52:08 UTC (2024-10-01) · approx. 8:52 AM UTC+10 local
On October 1, 2024 at 22:52 UTC, a magnitude 4.3 intermediate depth earthquake struck in the Volcano Islands, Japan region, at a depth of 99.6 km and coordinates 22.9349°, 143.3901°.
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.
