2024-09-13 22:11:02 UTC (2024-09-13) · approx. 7:11 AM UTC+9 local
On September 13, 2024 at 22:11 UTC, a magnitude 4.1 intermediate depth earthquake struck in the Izu Islands, Japan region, at a depth of 93.3 km and coordinates 29.9174°, 140.7676°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
