Tsunami hits coast of Japan after powerful earthquake

Tsunami waves of up to 1 metre have hit the coast of north-eastern Japan after a powerful earthquake, the Meteorological Agency said on Saturday. A magnitude-7.1 earthquake struck off the east coast of Japan's Fukushima region at 2:10 am (1710 GMT Friday), it said, adding that the damaged nuclear power plant there had not been affected.
The tremor's epicentre was located off Fukushima at a depth of 10 kilometres, the agency said. It had initially measured the earthquake at magnitude 6.8. The US Geological Survey measured the quake at magnitude 7.3 in the Pacific Ocean about 300 kilometres from Fukushima's coast.
