2024-07-10 18:47:39 UTC (2024-07-10) · approx. 3:47 AM UTC+9 local
On July 10, 2024 at 18:47 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Izu Islands, Japan region, at a depth of 14.1 km and coordinates 30.7475°, 139.6713°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
