On October 7, 2025 at 00:30 UTC, a magnitude 5.1 shallow crustal earthquake struck 27 km ENE of Namie, Japan, at a depth of 57.8 km and coordinates 37.5736°, 141.2916°. This earthquake was detected by 79 seismic stations with good location accuracy and was assigned a USGS significance rating of 405, placing it among routine seismic activity.

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.

Common Questions

How strong was the magnitude 5.1 earthquake near Namie, Japan?

The magnitude 5.1 earthquake that struck 27 km ENE of Namie, Japan on October 7, 2025 at 00:30 UTC had a depth of 57.8 km. For context, this was a moderate earthquake that could be widely felt.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks and gradually diminish over time.

Has Japan had earthquakes this big before?

The largest recorded earthquake in Japan was the M9.1 Tohoku earthquake of March 11, 2011. Today's magnitude 5.1 event is significantly smaller than that historical record.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
