M5.1 Earthquake 70 km W of Hirara, Japan — March 25, 2022
2022-03-25 03:08:55 UTC (2022-03-25) · approx. 11:08 AM UTC+8 local
On March 25, 2022 at 03:08 UTC, a magnitude 5.1 intermediate depth earthquake struck 70 km W of Hirara, Japan, at a depth of 71.2 km and coordinates 24.8602°, 124.6037°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
