A powerful 7.1-magnitude earthquake jolted Japan’s Kyushu region on Tuesday, centering on Kumamoto and triggering a brief tsunami advisory for nearby coasts before officials lifted it after no significant waves were observed. The shallow quake, which reached the highest levels of shaking in some areas, disrupted daily life across southern Japan: bullet trains were halted, power outages hit thousands of homes, and emergency warnings went out across multiple prefectures. Authorities also checked nuclear and industrial facilities, reporting no irregularities. Damage assessments were still unfolding, with reports ranging from collapsed stone walls at Kumamoto Castle to more serious claims of building collapses, fires and a partial failure at an Aeon shopping mall that may have trapped shoppers. With aftershocks expected, the broader story is one of a country’s rapid emergency systems once again being tested by the constant threat beneath its feet.
