Tens of thousands of soldiers are continuing their rescue and recovery mission in Japan, where more than 3,000 people are known to have died after Friday's 9.0-magnitude quake and tsunami.
Rivers of debris run through high streets all over the disaster zone, such as here in Kesennuma city, Miyagi prefecture.
Some cities and towns in north-eastern Japan were virtually wiped out by the devastating tsunami.

Thousands of people remain unaccounted for, and those left behind - such as this woman in Rikuzentakata city, Iwate prefecture - are scouring message boards for traces of vanished loves ones.
Poignant reminders of life before the tsunami litter the landscape, such as this muddy stuffed bear in a destroyed classroom in Higashimatsushima, Miyagi prefecture.
But there also have been happy family reunions of survivors after the deadly tsunami. This boy in Yamada, northern Japan, was reunited with his mother after four anxious days.
More than 500,000 people have been made homeless and are living in temporary evacuation centres, many without running water or power.
This woman, Fujiko Chiba, was rescued by Japanese soldiers in Ishimaki town, Miyagi prefecture, after five days stranded at an isolated evacuation centre.
Meanwhile, the Japanese authorities are seeking to allay fears following a third explosion and a fire at the Fukushima nuclear plant which was damaged in Friday's earthquake and tsunami.
Radiation leaking from the plant reached levels high enough to affect human health - but this warning was later revised as levels fell. The government said the radiation would only be dangerous if people were exposed to it for a sustained period of time.
Residents within 20km (12 mile) of the plant have already been advised to evacuate, and the premier said those living within between 20km and 30km of the plant were at risk and should stay indoors.
