Felt by 12 people across nearby locations.
On April 5, 2022 at 15:03 UTC, a magnitude 4.8 shallow crustal earthquake struck 66 km ENE of Namie, Japan, at a depth of 53.6 km and coordinates 37.8085°, 141.6288°.
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.
