2023-05-25 20:53:53 UTC (2023-05-25) · approx. 5:53 AM UTC+9 local
On May 25, 2023 at 20:53 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Izu Islands, Japan region, at a depth of 10.0 km and coordinates 32.6270°, 141.8022°.
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.
