M5.3 Earthquake 10 km N of Aso, Japan — November 25, 2025
2025-11-25 09:01:17 UTC (2025-11-25) · approx. 6:01 PM UTC+9 local
Felt by 14 people across nearby locations. Maximum shaking intensity MMI 6.6 (very strong).
On November 25, 2025 at 09:01 UTC, a magnitude 5.3 shallow crustal earthquake struck 10 km N of Aso, Japan, at a depth of 10.0 km and coordinates 33.0317°, 131.0814°. The earthquake was reported felt by 14 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.6 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 186 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 442, placing it among routine seismic activity. The nearest populated place is Aso (population 27,978).
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.3 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 5.3 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.
