Tokyo, Aug 19: Japan has issued tsunami alert after a strong 6.8-magnitude earthquake hit off the northeast coast.
A strong earthquake with a preliminary magnitude of 6.8 jolted northeastern Japan off Fukushima prefecture on Friday and a 50 cm tsunami advisory was issued for the coast of Miyagi and Fukushima prefectures, the Japan Meteorological Agency said.
