A powerful 7.1-magnitude earthquake has struck Japan's southwestern Kumamoto region, leaving at least 13 people dead and dozens injured. Homes were flattened, roads cracked, bridges damaged, and a shopping mall was devastated by a suspected gas explosion shortly after the quake. More than 9,000 people have taken shelter in evacuation centres, while thousands remain without electricity. Rescue teams continue searching for missing people trapped under collapsed buildings as Japan deploys military personnel and emergency responders across the disaster zone.
