Strong quake hits Japan, triggers Fukushima tsunami
A powerful 6.9-magnitude earthquake hit northeast Japan on Tuesday, sparking panic and triggering a tsunami including a one-metre (three-foot) wave that crashed ashore at the stricken Fukushima nuclear power plant. National broadcaster NHK urged residents to "flee immediately" to higher ground, reminding viewers to heed the lessons of the "Great East Japan Earthquake". A massive undersea quake with a magnitude of 9.0 that struck in March 2011 unleashed a tsunami that left more than 18,500 people dead or missing.
