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.
Tensions in Japan over this tsunami warning must be great as the Japanese people are still struggling to recover from the previous earthquake and tsunami.
