Quake Rocks Japan

A tsunami warning has been issued after a 6.9 magnitude earthquake struck off the coast of Japan. The quake hit this morning, 67 km northeast of Iwaki and at a depth of 10km, the US Geological Survey said. It was originally thought to be a 7.3 magnitude quake, but was quickly downgraded. Civil Defence said there was no tsunami threat to New Zealand. Former RNZ reporter, Chris Gilbert, is in Tokyo.
