M4.7 Earthquake 39 km NNE of Kuji, Japan — June 25, 2026
2026-06-25 16:11:44 UTC (2026-06-25) · approx. 1:11 AM UTC+9 local
On June 25, 2026 at 16:11 UTC, a magnitude 4.7 shallow crustal earthquake struck 39 km NNE of Kuji, Japan, at a depth of 61.7 km and coordinates 40.4996°, 141.9882°. This earthquake was detected by 71 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Japan, a region characterized by the intersection of four tectonic plates — Pacific, Philippine Sea, Eurasian, and North American — creating multiple subduction zones. The nearest mapped fault system is the Japan Trench. View all earthquakes in Japan.
