Japan marks earthquake anniversary with minute's silence
The moment Japan was struck by the biggest earthquake it has ever experienced has been marked by a minute's silence during a memorial service in Tokyo.
The earthquake hit at 14:46 local time (05:46 GMT) about 400km (250 miles) north-east of Tokyo on 11 March 2011.
Shortly after the quake, an immense surge of water enveloped the north-eastern coast as a tsunami swept cars, ships, and buildings away, crushing coastal communities.
More than 15,800 lives were lost in the twin disasters, and more than 3,000 people remain unaccounted for.
