Today, March 11th marks the first anniversary of the horrific earthquake and tsunami that devastated the coastline of north-eastern Japan. The Japanese government will hold a memorial service at the National Theatre, which faces the Imperial Palace grounds in Tokyo to mourn the disaster. At 2.46pm trains will stop, shoppers will stand still and people throughout Japan will fall silent to mark the exact moment when the 9.0 magnitude quake set off a catastrophic chain of events.
