Japan was assessing damage Tuesday and cautioning people of potential aftershocks after a late-night 7.5 magnitude earthquake caused injuries, light damage and a tsunami in Pacific coastal communities.

Axar.az informs, citing AP, at least 33 people were injured, one seriously, the Fire and Disaster Management Agency said. Most of them were hit by falling objects, public broadcaster NHK reported.

Prime Minister Sanae Takaichi told reporters an emergency task force was formed to urgently assess damage. “We are putting people’s lives first and doing everything we can,” she said.

At a parliamentary session Tuesday, Takaichi pledged the government would continue its utmost effort and reminded people they have to protect their own lives.

The 7.5 magnitude quake struck around 11:15 p.m. in the Pacific Ocean, around 80 kilometers (50 miles) off the coast of Aomori, the northernmost prefecture of Japan’s main Honshu island. The U.S. Geological Survey measured the quake at 7.6 magnitude and said it occurred 44 kilometers (27 miles) below the surface.

A tsunami of up to 70 centimeters (2 feet, 4 inches) was measured in Kuji port in Iwate prefecture, just south of Aomori, and waves up to 50 centimeters struck other communities in the region, the Japan Meteorological Agency said.
