6.9 quake triggers Japan tsunami

A powerful 6.9-magnitude earthquake hit northeast Japan on Tuesday, sparking panic and triggering a tsunami including a one-metre wave that crashed ashore at the stricken Fukushima nuclear power plant. There were no immediate signs of widespread damage and only minor injuries were initially reported. A 9.0 quake in March 2011 unleashed a tsunami in Japan that left more than 18,500 people dead or missing.
