LONDON -- A magnitude 7.1 earthquake rocked southern Japan on Tuesday, prompting the Japan Meteorological Agency to issue a tsunami advisory for the coasts of the Ariake Sea and the Yatsushiro Sea.
The earthquake occurred in Kumamoto Prefecture at a depth of just over 6 miles, according to the United States Geological Survey.
Japan's Nuclear Regulation Authority said in an emergency update that it had not recorded "abnormalities" at nearby facilities in Ikata and Genkai.
There are no reports of damage but officials have urged people to stay away from the ocean and the sea shore.
