Powerful earthquake strikes Japan

Friday 11 March 2011 04.11 EST

A series of massive earthquakes have struck north-east Japan, unleashing a 10-metre tsunami that swept buildings, vehicles, crops and debris across swaths of farmland.

The first 8.9 magnitude shock is said to be the biggest to have hit Japan in 140 years, rocking buildings 235 miles (380km) away in Tokyo and sparking fires.

At least five people are known to have died, but amid widespread reports of landslides, floods, collapsed buildings and fires, the death toll is expected to rise.

The quake hit at 2.46pm (5.45am GMT), about 6 miles below sea level and 78 miles off the east coast. It was swiftly followed by five powerful aftershocks of up to 7.1 magnitude. In Tokyo people screamed and grabbed each other's hands as the quake struck. The shock was so powerful it was felt as far away as Beijing.
