A sharp, violent jolt tore through southern Japan late this afternoon, as a magnitude 7.1 earthquake (recorded as 6.8 by the U.S. Geological Survey) struck beneath Kumamoto Prefecture at 4:27 p.m. local time.
The tremor, centred near the city of Uki at a shallow depth of roughly 10 kilometres, registered the maximum intensity of 7 on Japan’s seismic scale in parts of the prefecture—strong enough to fling people from their feet and send buildings lurching.
The most dramatic and tragic scene unfolded at the Aeon Mall in Kashima Town, southeast of Kumamoto City. Shortly after the main shock, an explosion—widely reported as linked to a suspected gas leak—ripped through the complex.
The second floor partially collapsed, scattering debris across the car park and trapping an estimated 20 to 30 people, many of them staff who had remained inside after the initial evacuation of shoppers.
Rescue teams, supported by fire services and the Self-Defence Forces, worked into the evening under the threat of aftershocks.
Early reports spoke of multiple deaths and several people still unaccounted for, though exact numbers remained fluid as the search continued.
Across the prefecture the damage mounted quickly. Roads cracked and buckled, including sections of elevated highway.
A portion of a historic castle wall came down. A chimney collapsed at a paper factory, leaving several workers missing. Power failed for some 40,000 households, mobile networks faltered in places, and a freight train was derailed. At least 50 people were reported injured in the first hours, with the toll expected to rise.
Factories belonging to TSMC, Sony and Fujifilm temporarily evacuated staff. Roughly 150,000 to 300,000 residents were advised to seek shelter as aftershocks—more than 60 of them, some reaching magnitude 4—kept the ground restless.
A tsunami advisory for the Ariake and Yatsushiro Seas was issued and then lifted within two hours; no significant wave was detected.
Prime Minister Sanae Takaichi addressed the nation, comparing the event to the deadly 2016 Kumamoto earthquakes and urging residents to stay vigilant and move to safety. “Human casualties, building collapses, road damage, fires and other damages have been confirmed,” she said, promising an all-night effort to assess the full scale of the disaster.
For a region that has only recently finished rebuilding from the 2016 sequence—itself the deadliest in Japan since the 2011 Tōhoku catastrophe—the return of such force carried a bitter familiarity. Night fell on scenes of rubble, emergency lights, and the steady work of rescuers picking through the wreckage of the mall, while residents waited for the earth to settle once more.
