Powerful 7.1 Magnitude Earthquake Strikes Southern Japan, Triggering Tsunami Alert

A powerful 7.1 magnitude earthquake struck southern Japan on Tuesday, causing widespread damage, disrupting transportation and power supplies, and prompting a tsunami advisory for coastal areas as emergency crews rushed to assess the extent of the disaster.

The earthquake struck at approximately 4:27 p.m. local time near the city of Uki in Kumamoto Prefecture on Japan’s southern island of Kyushu. The tremor originated at a shallow depth of around 10 kilometres and registered the maximum level of 7 on Japan’s Shindo seismic intensity scale in parts of Kumamoto, indicating extremely violent shaking.

Japanese authorities immediately issued a tsunami advisory for coastal areas bordering the Ariake and Yatsushiro seas, warning residents to move away from shorelines. The advisory was lifted less than two hours later after no significant tsunami waves were observed. The U.S. Pacific Tsunami Warning Center also confirmed there was no wider tsunami threat beyond Japan’s local coastline.

Prime Minister Sanae Takaichi activated the government’s emergency response, confirming reports of injuries, collapsed buildings, fires, damaged roads and widespread power outages. Rescue operations were launched after part of a shopping mall in Kashima Town collapsed, leaving several people trapped beneath the rubble. Authorities also reported a derailed train, structural damage to historic buildings including Kumamoto Castle, and the suspension of bullet train services across the region. Kumamoto Airport was temporarily closed as emergency inspections got underway.

Nearly 50,000 households reportedly lost electricity following the quake, while emergency shelters were opened for residents displaced or fearful of aftershocks. Officials urged the public to remain vigilant, warning that strong aftershocks could continue over the coming days and increase the risk of landslides and additional structural failures.

Japan’s Nuclear Regulation Authority said inspections found no abnormalities at nearby nuclear power facilities, easing fears of a repeat of the country’s 2011 Fukushima nuclear disaster.

The latest earthquake struck almost exactly a decade after the devastating 2016 Kumamoto earthquakes, which claimed more than 270 lives and caused extensive destruction throughout the prefecture. Japan, situated along the seismically active Pacific Ring of Fire, experiences thousands of earthquakes each year and remains one of the world’s most earthquake-prone nations.

Authorities continue to assess the full scale of the damage while search and rescue efforts remain underway in the affected communities.
