Earthquakes in Fukuoka
Fukuoka, Kyushu's largest city with 1.5 million residents, experienced a significant M7.0 earthquake in 2005 that struck just offshore in the Genkai Sea, causing damage and one fatality. The city sits in a seismically active region where multiple fault systems cross Kyushu island.
Why Does Fukuoka Face Earthquake Risk?
Kyushu island contains a network of active faults related to the back-arc extension of the Ryukyu arc. The Kego Fault runs directly beneath central Fukuoka. The 2016 Kumamoto earthquake sequence demonstrated the seismic hazard across Kyushu when a M7.0 struck 100 km to the southeast.
Active Fault Systems
- Kego Fault
- Rausu Fault
- Itoshima Fault
Safety Advice
Fukuoka City publishes detailed hazard maps for earthquake and liquefaction risk. The Kego Fault poses the greatest direct threat to the urban center. Register with Fukuoka's disaster alert system for mobile earthquake notifications.
Historical Earthquake Context
The March 2005 Fukuoka earthquake (M7.0) struck the Genkai Sea 60 km northwest of the city, killing 1 person and injuring 1,000. The earthquake caused significant damage to older buildings and highlighted fault hazards previously considered less threatening in Kyushu.

FAQ
Frequently Asked Questions
What earthquake hit Fukuoka in 2005?
A M7.0 earthquake struck the Genkai Sea northwest of Fukuoka on March 20, 2005, killing 1 person and injuring over 1,000. The earthquake damaged hundreds of buildings and created widespread panic in the city.
How seismically active is Fukuoka?
Fukuoka has relatively lower seismic activity compared to other major Japanese cities but is not immune. The 2005 event demonstrated that offshore faults in the Genkai Sea can damage the city. The Kego Fault passes beneath central Fukuoka and is capable of a M7.2+ earthquake at close range.
Is Fukuoka prepared for a major earthquake?
Yes. Fukuoka strengthened preparedness after the 2005 event with revised building codes, expanded seismic retrofitting subsidies, and improved emergency infrastructure. The Kego Fault's proximity to the city center means any future rupture would affect densely built areas.
What should I do during an earthquake in Fukuoka?
Drop, Cover, and Hold On under a sturdy table or against an interior wall. After shaking stops, exit buildings carefully. Japan's EEW system may deliver mobile alerts seconds before strong shaking arrives. Monitor JMA and city emergency broadcasts for aftershock information.
Where can I see live earthquake data for Fukuoka?
Track earthquakes near Fukuoka on the Earthquake Globe app or at earthquakes.site/map?country=japan. Japan's Meteorological Agency (JMA) at jma.go.jp provides official real-time seismic data. Enable J-Alert on your smartphone for official early warnings.
