Tsunami Earth Quake in Japan Awareness Photos

Japan's most powerful earthquake since records began has struck the north-east coast, triggering a massive tsunami.

Cars, ships and buildings were swept away by a wall of water after the 8.9-magnitude tremor, which struck about 400km (250 miles) north-east of Tokyo.

A state of emergency has been declared at a nuclear power plant but officials said there were no radiation leaks.

Officials say 350 people are dead and about 500 missing, but it is feared the final death toll will be much greater.
