On January 26, 2025 at 16:31 UTC, a magnitude 4.8 shallow crustal earthquake struck 38 km NNE of Hirara, Japan, at a depth of 35.0 km and coordinates 25.0985°, 125.5015°. This earthquake was detected by 61 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 355, 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.
