A preliminary magnitude 7.1 earthquake struck off Japan’s southern main island of Kyushu on Tuesday afternoon, with its epicentre located 10 km beneath the seabed, according to the Japan Meteorological Agency (JMA). Public broadcaster NHK reported that the quake was felt in Kumamoto Prefecture, prompting the JMA to issue a tsunami advisory for coastal areas along the Ariake Sea and the Yatsushiro Sea.

Japan’s Prime Minister Sanae Takaichi urged residents to stay away from the coastline after authorities warned of a tsunami of up to one metre (3 feet) following the powerful earthquake, Associated Press reported.
In a post on X, she said the government had set up a task force to gather information, assess the extent of the damage and coordinate rescue operations if required.
“We are putting people’s lives as the top priority,” Takaichi said, while urging those in the worst-hit areas to remain alert for strong aftershocks.

The Fire and Disaster Management Agency reported no immediate report of damage to major public infrastructure.
As a precaution, Shinkansen bullet trains and local rail services across Kyushu were temporarily suspended for safety checks.
The Nuclear Regulation Authority said inspections found no abnormalities at three nearby nuclear power plants, reported AP.
Meanwhile, the Defence Ministry dispatched aircraft to survey the affected areas and assist with damage assessment.
The quake struck the same region that was devastated by the 2016 Kumamoto earthquake, which killed more than 50 people, injured around 1,800 and damaged or destroyed tens of thousands of homes.
