The second floor of the Aeon Mall in Kashima Town collapsed, trapping an unknown number of individuals inside. Rescue operations were ongoing, as reported by the Fire and Disaster Management Agency. An explosion was noted prior to the collapse, according to the Kyodo News Agency.
A tsunami advisory was momentarily in effect for the Ariake and Yatsushiro Seas near Kumamoto and three adjacent prefectures. The advisory lifted within two hours, the Japan Meteorological Agency stated.

The U.S. Geological Survey initially marked the earthquake at a magnitude of 7.1, later revising this to 6.8. The region affected is located approximately 900 kilometers southwest of Tokyo.

Japan’s Prime Minister Sanae Takaichi informed through a message on X about the establishment of a task force to gather information and assess damage. Reports indicated injuries, along with damage to roads, bridges, and buildings.
Blackouts and fires have also been reported. Takaichi advised people to be cautious with fire and broken glass. About 40 injured individuals were received by a hospital in Yatsushiro city.

The Fire and Disaster Management Agency confirmed no major damage to public infrastructure, although local emergency services received numerous calls reporting fires and home damage.
