In March 2011, about 18,000 people had died when a 9.0 magnitude sub-sea earthquake sent a towering tsunami barreling into Japan's northeast coast in the country's worst post-World War II disaster. Cooling systems at the Fukushima nuclear plant had stopped working due to the sea wave invasion, sending reactors into meltdown mode and forcing tens of thousands of people to flee.
Japan's Islands have a long history of earthquakes and seismic activities as it is located near major tectonic plate boundaries and is situated on the Pacific Ring of Fire.
