Estimates say up to 88,000 missing in Japan tsunami

The biggest earthquake on record to hit Japan rocked its northeast coast on Friday, triggering a 10-metre tsunami that killed hundreds of people and swept away everything in its path.

Thousands of residents near a nuclear plant in Fukushima prefecture, north of Tokyo, were told to evacuate as a precaution after the 8.9 magnitude quake, but the government said no radiation was leaking.

Up to 300 bodies were found in the coastal city of Sendai, media said. NHK television said the victims appeared to have drowned. The extent of the destruction along a lengthy stretch of coastline suggested the death toll could rise significantly.

Tsunami warnings were issued across the Pacific but were later lifted for some of the most populated countries in the region, including Australia, Taiwan and New Zealand.

Other Japanese nuclear power plants and oil refineries were shut down and one refinery was ablaze. Television footage also showed an intense fire in the waterfront area near Sendai, the city hardest hit by the quake.

A major explosion hit a petrochemical complex in Miyagi prefecture after the quake, Kyodo said.

Political leaders pushed for an emergency budget to help fund relief efforts after Prime Minister Naoto Kan asked them to "save the country", Kyodo news agency reported.

Stunning TV footage showed a muddy torrent of water carrying cars and wrecked homes at high speed across farmland near Sendai, home to one million people and which lies 300 km (180 miles) northeast of Tokyo. Ships had been flung onto a harbour wharf, where they lay helplessly on their side.

The quake, the most powerful since Japan started keeping records 140 years ago, sparked at least 80 fires in cities and towns along the coast, Kyodo news agency said.

A ship carrying 100 people had been swept away by the tsunami, Kyodo said. One train was derailed and another unaccounted for.

In Tokyo, residents who had earlier fled swaying buildings jammed the streets trying to make their way home after much of the city''s public transportation was halted. There have been several strong aftershocks. In Tokyo, there was widespread panic. An oil refinery near the city was on fire, with dozens of storage tanks under threat. Around 4.4 million homes were without power in northern Japan, media said.
