2026-08-02 00:45:40 UTC (2 hours ago) · approx. 10:45 AM UTC+10 local
On August 2, 2026 at 00:45 UTC, a magnitude 4.8 shallow crustal earthquake struck 64 km ENE of Noda, Japan, at a depth of 56.4 km and coordinates 40.3020°, 142.5317°. This earthquake was detected by 71 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
