Felt by 11 people across nearby locations.
On July 5, 2022 at 20:10 UTC, a magnitude 5.3 intermediate depth earthquake struck 63 km E of Ishinomaki, Japan, at a depth of 73.6 km and coordinates 38.4394°, 142.0322°. This earthquake was detected by 250 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 437, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
