Strong quake shakes Tokyo region

Posted 1 hour 5 minutes ago

A strong quake was felt late on Tuesday in Tokyo, shaking buildings in Japan's capital four days after a massive tremor sparked a devastating tsunami that ravaged the country's north-east coast.

The Japan Meteorological Agency put the magnitude of the quake at 6.0.

The epicentre was located in Shizuoka prefecture, about 120 kilometres south-west of the capital, and near Mount Fuji, which is prone to earthquakes.

The quake occurred at a relatively shallow depth of 10 kilometres.
