2026-03-09 20:05:59 UTC (2026-03-09) · approx. 5:05 AM UTC+9 local
On March 9, 2026 at 20:05 UTC, a magnitude 4.4 shallow crustal earthquake struck 58 km SE of Taira, Japan, at a depth of 10.0 km and coordinates 26.2362°, 128.5438°.
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.
