M4.9 Earthquake 53 km SSW of Shizunai-furukawach?, Japan — June 10, 2022
2022-06-10 02:14:06 UTC (2022-06-10) · approx. 11:14 AM UTC+9 local
Felt by 2 people across nearby locations. Aftershock of the M6.0 mainshock.
On June 10, 2022 at 02:14 UTC, a magnitude 4.9 shallow crustal earthquake struck 53 km SSW of Shizunai-furukawach?, Japan, at a depth of 65.2 km and coordinates 41.8708°, 142.2015°. This earthquake was detected by 111 seismic stations with good location accuracy and was assigned a USGS significance rating of 370, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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 6.0 mainshock that occurred 18 days ago 32 km SSW of Honchō, Japan. Since the mainshock, the USGS has recorded 0 aftershocks in this area. Aftershock activity is expected to continue for weeks to months 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 4.9 earthquake near Shizunai-furukawach?, Japan?
The magnitude 4.9 earthquake that struck 53 km SSW of Shizunai-furukawach?, Japan on June 10, 2022 at 02:14 UTC had a depth of 65.2 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 41.8708°, 142.2015°, which is 53 km SSW of Shizunai-furukawach?, Japan. View all earthquakes in Japan.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M6.0 one earlier?
No. This magnitude 4.9 earthquake is an aftershock of the larger magnitude 6.0 mainshock that occurred earlier 32 km SSW of Honchō, 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 4.9 event is significantly smaller than that historical record.
