2024-03-15 23:24:51 UTC (2024-03-15) · approx. 9:24 AM UTC+10 local
On March 15, 2024 at 23:24 UTC, a magnitude 4.4 shallow crustal earthquake struck 171 km E of Noda, Japan, at a depth of 10.0 km and coordinates 40.3498°, 143.8040°.
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.
