The national meteorological agency issued a tsunami advisory that was later lifted after a magnitude 6.8 earthquake struck off the northeastern coast of Japan. A quake measuring 6.1 later hit eastern Japan.
RT reported this morning that the earlier quake happened at a depth of some 10 km.
The tsunami warning was intended for the coastal Aomori and Iwate prefectures.
However, the estimated height of the wave is small, at approximately 50 centimeters.
A later quake measuring 6.1 struck eastern Japan. No abnormalities were reported at the Tokai No.2 nuclear power plant northeast of Tokyo, Reuters writes.
Japan was hit by a 9.0 earthquake on 11 March 2011 and the resulting tsunami led to thousands losing their lives.
