A powerful 7.0-magnitude earthquake struck early Saturday off the southwest coast of Japan, but there were no reports of damage or injuries.
The earthquake struck at 5:51 a.m. (20:51 GMT) at a depth of 10 kilometers (6 miles), about 190 kilometers (118 miles) southwest of Kagoshima city, the Japan Meteorological Agency said.
A 30-centimeter (1-foot) tsunami was recorded at 6:45 a.m. on Nakanoshima, a small island to the south of Kyushu, Japan's southernmost main island. A tsunami advisory for Kagoshima prefecture and a string of small islands was lifted at 7:20 a.m.
Two nuclear reactors on Kyushu island were not affected by the incident, the plants' operator said.
Tetsuro Shinchi, a Kagoshima prefectural government official, said that although there had been no reports of damage, residents were being urged to use caution.
A 2011 earthquake and tsunami near northeast Japan killed thousands of people.
