M5.1 Earthquake 111 km E of Yamada, Japan — November 10, 2025
2025-11-10 09:58:59 UTC (2025-11-10) · approx. 7:58 PM UTC+10 local
Aftershock of the M5.2 mainshock.
On November 10, 2025 at 09:58 UTC, a magnitude 5.1 shallow crustal earthquake struck 111 km E of Yamada, Japan, at a depth of 13.7 km and coordinates 39.5843°, 143.2329°. This earthquake was detected by 78 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, 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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.2 mainshock that occurred 20 days ago 103 km ENE of Miyako, Japan. Since the mainshock, the USGS has recorded 2 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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 Yamada, Japan?
The magnitude 5.1 earthquake that struck 111 km E of Yamada, Japan on November 10, 2025 at 09:58 UTC had a depth of 13.7 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at 39.5843°, 143.2329°, which is 111 km E of Yamada, Japan. View all earthquakes in Japan.
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.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 5.1 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 103 km ENE of Miyako, Japan. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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.
