Aftershock of the M5.3 mainshock.
On June 18, 2025 at 12:30 UTC, a magnitude 4.8 shallow crustal earthquake struck 34 km ESE of Takanabe, Japan, at a depth of 51.4 km and coordinates 32.0487°, 131.8488°. This earthquake was detected by 73 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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 5.3 mainshock that occurred 11 hours ago 44 km ESE of Miyazaki, 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 4.8 earthquake near Takanabe, Japan?
The magnitude 4.8 earthquake that struck 34 km ESE of Takanabe, Japan on June 18, 2025 at 12:30 UTC had a depth of 51.4 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 32.0487°, 131.8488°, which is 34 km ESE of Takanabe, Japan. View all earthquakes in Japan.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.8 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.3 one earlier?
No. This magnitude 4.8 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 44 km ESE of Miyazaki, 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 4.8 event is significantly smaller than that historical record.
