Powerful quake rocks Tokyo

A major 7.0-magnitude earthquake rocked Tokyo yesterday as Emperor Akihito led Japan's New Year celebrations by urging people to work together in rebuilding the nation from March's quake-tsunami disaster.
The tremor struck at 2:28pm local time with its focus deep at about 370 kilometres, Japan's Meteorological Agency said. The US Geological Survey put the depth at 348 kilometres.
Its epicentre was located near Torishima, a northwestern Pacific island about 560 kilometres south of Tokyo.
There were no immediate reports of damage or injury and no tsunami warning was issued.
