Japan earthquake: Struggle to reach tsunami survivors

A municipal official of the town of Futaba in Fukushima prefecture said: ''More than 90% of the houses in three coastal communities have been washed away by tsunami. Looking from the fourth floor of the town hall, I see no houses standing.'' In one of the worst-hit areas of Fukushima prefecture, people buried under rubble could be heard calling out for help, the Kyodo news agency reported. Four trains running in a coastal area of Miyagi and Iwate prefectures are still unaccounted for. In Ibaraki prefecture, north-east of Tokyo, many homes are still without power and there are queues at the few petrol stations that are open, says the BBC's Chris Hogg.
