2024-03-02 23:09:54 UTC (2024-03-02) · approx. 8:09 AM UTC+9 local
On March 2, 2024 at 23:09 UTC, a magnitude 4.8 intermediate depth earthquake struck 113 km WNW of Uken, Japan, at a depth of 165.4 km and coordinates 28.8025°, 128.2279°. This earthquake was detected by 116 seismic stations with excellent 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.
