Huge earthquake and tsunami in Japan

There has been a very big earthquake in the sea outside the Japanese east coast. The earthquake apparently measured 8.8 on the Richter scale and has also produced a tsunami which hit part of the northeastern coast of Japan with waves up to ten metres in height. The city of Sendai and the Miyagi prefecture seem to be severely hit while large parts of eastern Honshu, including Tokyo, have been affected to different degrees.
