2026-08-01 19:10:52 UTC (1 hour ago) · approx. 4:10 AM UTC+9 local
On August 1, 2026 at 19:10 UTC, a magnitude 5.2 shallow crustal earthquake struck 48 km ESE of Tsunō, Japan, at a depth of 26.2 km and coordinates 32.0078°, 131.9999°. This earthquake was detected by 83 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
