Strong 7.0-magnitude quake hits off Japan coast: USGS
http://news.yahoo.com/strong-7-0-magnitude-quake-hits-off-japan-211816995.html
A powerful 7.0-magnitude earthquake struck off the southwestern coast of Japan early Saturday, the US Geological Survey (USGS) said, with Japanese authorities reporting several small tsunamis on at least two islands.

The USGS put the epicentre of the shallow quake about 160 kilometres (100 miles) from the town of Makurazaki in southwest Japan, though no major damage was initially reported.

yes, initially reported as a 7.0 followed by a 6.5 30 sec later, was revised down to a single 6.7 event after around 30 mins
