11.03.2011 - Fukushima nuclear disaster
Northeast Japan experiences the strongest earthquake in Japanese history (magnitude 9). This leads to severe destruction and triggers a tsunami that devastates coastal areas with 14 foot waves. More than 18,000 people die. In addition, the nuclear power complex Fukushima-Daichi is severely damaged by the quake and flooding. This leads to a serious accident and subsequent meltdown of reactor cores. Several explosions release large volumes of radioactive material into the air. The area around the nuclear power plant is contaminated.
