A powerful 6.8 magnitude earthquake struck Japan’s Kumamoto prefecture on Tuesday, killing at least 13 people and forcing roughly 300,000 residents to evacuate. The quake, centered near the coastal city of Uto about 30 miles southwest of Kumamoto City, collapsed multiple buildings including a shopping mall where 20 to 30 employees remain unaccounted for. Rescue crews continued overnight searches as aftershocks up to magnitude 5.6 rattled the region.
What happened in Kumamoto
The earthquake struck at 4:27 p.m. local time on Tuesday with a preliminary magnitude of 7.1, later revised to 6.8 by the U.S. Geological Survey. The epicenter was about 12 miles south of Kumamoto City, a metropolitan area of roughly 700,000 people on Kyushu, Japan’s southwestern main island. The quake’s depth was just over 6 miles, and it was strong enough to be felt in South Korea. A tsunami advisory was issued but lifted within two hours.
Damage and casualties mount
At least 13 people have been confirmed dead. A second-floor explosion at the Aeon Mall shopping center in Kashima Town trapped an unknown number of shoppers and employees. About 80 people were being treated at Yatsushiro Northern Regional Medical Center, and around 10 more were injured at a nursing home in Hikawa. At least 12 houses collapsed, and widespread damage occurred to roads, bridges, and buildings.
Aftershocks and infrastructure impact
At least six additional quakes with magnitudes ranging from 4.4 to 5.6 struck the region after the main quake. A train derailed and fell on its side at Yatsushiro station, and stone walls were damaged at Kumamoto Castle. Power outages affected thousands of homes. Shinkansen bullet trains and local trains in Kyushu were suspended for safety checks, and Aso Kumamoto Airport’s runway was closed with no prospect of resuming operations.
Regional context and preparedness
Kumamoto prefecture sits on Japan’s Ring of Fire, where tectonic plates converge and tremors occur almost constantly. The region experienced a disastrous set of quakes in 2016 that killed hundreds and injured thousands. Japan’s Nuclear Regulation Authority reported no abnormalities at three nearby nuclear power plants, including the Sendai Nuclear Power Plant in neighboring Kagashima prefecture. Prime Minister Sanae Takaichi warned about heatstroke risks in disaster-stricken areas facing power outages and water shortages.
Final Thoughts
The Kumamoto earthquake ranks among Japan’s most significant seismic events in recent years. With rescue operations ongoing and aftershocks continuing, officials face a critical window to locate missing persons and restore critical infrastructure to a region still recovering from 2016’s devastating quakes.
