Thousands displaced as aftershocks rattle Kyushu, power cut to 40,000 homes, and 3,600 soldiers deployed for recovery across southern Japan

A powerful magnitude 7.1 earthquake struck Japan's southern Kumamoto prefecture on Tuesday afternoon, triggering an explosion at a shopping mall where police say several people are presumed dead and others remain trapped. The tremor knocked out electricity to approximately 40,000 homes, derailed a high-speed train, and forced the evacuation of around 300,000 residents.

The earthquake, centred in the city of Uki at a shallow depth of 10 kilometres, has paralysed transport across the Kyushu region and raised urgent concerns about aftershocks. Prime Minister Sanae Takaichi has mobilised 3,600 soldiers and urged residents to remain vigilant, warning that another quake of similar magnitude could follow.

Casualties and Immediate Damage

  • Several people are presumed dead and others remain trapped following an explosion at the Aeon Mall in Kumamoto city. An Aeon spokesperson confirmed customers and employees were evacuated after the initial quake, but the cause of the subsequent blast remains unclear.
  • One hospital in the region reported more than 50 injuries, according to public broadcaster NHK. Additional injuries occurred when tremors derailed a high-speed train.
  • Kyushu Electric Power reported approximately 40,000 homes lost electricity. Roads were ruptured, bridges damaged, and buildings collapsed across the affected zone.
  • Some portions of the stone walls at the already-under-repair Kumamoto Castle collapsed as a result of Tuesday's quake.

Japan's Seismic Vulnerability

Japan sits along the Pacific "Ring of Fire," a zone of volcanoes and oceanic trenches that accounts for roughly 20 percent of the world's earthquakes of magnitude 6 or greater. The country experiences a tremor at least every five minutes, making it one of the most seismically active nations on Earth.

Tuesday's disaster struck the same prefecture that was devastated by two large earthquakes a decade ago. Those twin quakes in Kumamoto killed 275 people and injured 2,739, according to official tallies. The region has been in a state of ongoing recovery ever since, with the historic Kumamoto Castle still undergoing repairs when the latest tremor caused further collapse.

Witness Accounts and Official Response

Kazuya Tsurunaga, who was cleaning up broken dishes at a pub roughly 300 metres from the Aeon Mall, described the explosion to broadcaster TBS: "It was a huge impact. A large cloud of smoke billowed up, and because the wind happened to be blowing and the wind direction was towards the shop, the area around us was in a state like volcanic ash was falling."

Prime Minister Takaichi addressed the nation, stating: "We have already been informed that people have been injured. Power outages and fires have occurred in some areas, and there has also been damage to roads and bridges and the collapse of buildings." She urged residents in affected areas to evacuate to safe locations. The Japan Times reported strong shaking was felt across Kumamoto and the neighbouring prefectures of Nagasaki, Kagoshima, Fukuoka, Saga, and Miyazaki.

Ongoing Recovery and Safety Measures

A tsunami warning issued immediately after the quake was later lifted. Japan's Nuclear Regulation Authority confirmed no abnormalities were detected at three nearby nuclear power plants. Shinkansen bullet trains and local rail services across Kyushu remain suspended for safety inspections, while Aso Kumamoto Airport has closed its runway with no immediate prospect of resuming operations.

Major manufacturers including Sony, TSMC, and Fujifilm evacuated staff from their plants in the affected area, though no damage to industrial infrastructure has been confirmed. Prime Minister Takaichi said the government is working to assess the full extent of the damage "as quickly as possible" while aftershocks continue to rumble through the region.
