Japan, which is yet to recover fully from the last yearâ€™s deadly earthquake and tsunami, was rocked by an earthquake of a 6.8 magnitude today.
There are no immediate reports of loss of life or property, officials said in Tokyo.
The Japanese Meteorological Agency immediately issued a tsunami threat and warned people that tsunami waves up to a height of 50 centimeter would hit the coast areas of Iwate and Aomori.
The epicenter of the quake was traced to a nearby area of Aomori prefecture at a depth of 10 km.
North-eastern parts of Japan were badly hit by a powerful earth quake of a 9.0 magnitude followed by a demonic tsunami on March 11, 2011 leaving more than 15,800 dead and nearly 3,300 missing. (J)
