M5.0 Earthquake 50 km ENE of Onagawa Chō, Japan — June 14, 2025
2025-06-14 10:47:01 UTC (2025-06-14) · approx. 7:47 PM UTC+9 local
Felt by 2 people across nearby locations. Aftershock of the M5.1 mainshock.
On June 14, 2025 at 10:47 UTC, a magnitude 5.0 shallow crustal earthquake struck 50 km ENE of Onagawa Chō, Japan, at a depth of 58.4 km and coordinates 38.5813°, 142.0012°. This earthquake was detected by 79 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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 5.1 mainshock that occurred 22 days ago 60 km SE of Ōfunato, Japan. Since the mainshock, the USGS has recorded 0 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 5.0 earthquake near Onagawa Chō, Japan?
The magnitude 5.0 earthquake that struck 50 km ENE of Onagawa Chō, Japan on June 14, 2025 at 10:47 UTC had a depth of 58.4 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at 38.5813°, 142.0012°, which is 50 km ENE of Onagawa Chō, Japan. View all earthquakes in Japan.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 5.0 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 60 km SE of Ōfunato, 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 5.0 event is significantly smaller than that historical record.
