2024-02-27 18:26:58 UTC (2024-02-27) · approx. 3:26 AM UTC+9 local
On February 27, 2024 at 18:26 UTC, a magnitude 4.2 intermediate depth earthquake struck 25 km NNW of Shimokizukuri, Japan, at a depth of 160.2 km and coordinates 41.0075°, 140.2106°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
