On March 11, 2011, a record 9.0-magnitude quake struck off the coast of Japan’s Tohoku region, triggering a tsunami with waves that reached a maximum height of 40.5 meters. Over 90% of the 15,900 deaths caused by the disaster were from drowning, and 2,520 people are still unaccounted for, according to Japan’s National Police Agency. The tsunami also caused a triple nuclear meltdown at the Fukushima No.1 nuclear plant –– the world’s first nuclear disaster since Chernobyl.

According to the Reconstruction Agency, 3,808 people died during evacuation or from other indirect causes, and 27,615 evacuees are still displaced. Of the displaced evacuees, there were about 19,673 people from Fukushima Prefecture, 846 people from Miyagi Prefecture and 529 people from Iwate Prefecture who evacuated to a different prefecture.
