TOKYO:-  A 6.0-magnitude earthquake hit off the coast of Fukushima in Japan on Friday but there was no risk of a tsunami, officials said. The quake hit at a relatively shallow depth of 10 kilometres (six miles) at 04:59 pm (0759 GMT), 255 kilometres east of Ishinomaki, according to the United States Geological Survey. The Japan Meteorological Agency said the quake posed no tsunami risk. A 9.0-magnitude earthquake in March 2011 triggered a massive and deadly tsunami, which smashed into the Fukushima nuclear power station and sparked the world’s worst atomic accident since Chernobyl in 1986.
