Aerial video of ravaged regions worst hit by Japan quake-tsunami

Vast areas in Japan have been left unrecognisable by the devastation caused by Friday's quake and tsunami. The coastline of Miyagi prefecture was one of the worst-hit regions. Police estimated 10-thousand dead among the 2.3 million people who lived in the prefecture, the Japanese equivalent of a state. On Monday, millions of people spent a fourth night with little food, water or heating in near-freezing temperatures as they dealt with the loss of homes and loved ones.
