A powerful tremor has occurred off the coast of Miyagi today at 14:45 local time, triggering a tidal wave on all the Pacific coast of Japan, as far south as the Philippines, and as far north as Russia. The tsunami exceeded 10 metres in height in North-East Japan, from Hokkaido to the Chiba prefecture. Sendai and many other places are under water and suffered considerable damage. Tokyo itself was left mostly unscathed by the waters (though shaken by the quake) thanks to the shelter provided by the Bay of Tokyo.
