An earthquake with a magnitude of 6.6 jolted southwestern Japan early on Saturday morning, injuring 13 people, the authorities and local media said.
No tsunami warning was issued after the quake struck with an epicentre 45 km (30 miles) deep at 1:08 a.m. (1608 GMT on Friday) off the coast of Kyushu, the southernmost of Japan’s four main islands, the Japan Meteorological Agency (JMA) said.
The quake caused shaking in Oita and Miyazaki prefectures that measured 5+ on Japan’s seismic intensity scale, which has a maximum of 7, the agency said.
Thirteen people were injured in nearby regions, including two people in their 80s who were seriously hurt, the Yomiuri newspaper reported, citing local authorities.
Multiple reports of damage to buildings, water pipes and roads have been confirmed, said public broadcaster NHK.
No abnormalities were reported at the Ikata nuclear power plant, operated by Shikoku Electric Power , or the Sendai plant operated by Kyushu Electric Power (9508.T) in southern Japan, the Nuclear Regulation Authority said.
