Destructive earthquakes, often resulting in tsunami, occur several times each century. The 1923 Tokyo earthquake killed over 140,000 people. More recent major quakes are the 1995 Great Hanshin earthquake and the 2011 Tōhoku earthquake, a 9.1-magnitude quake which hit Japan on March 11, 2011. It triggered a large tsunami and the Fukushima Daiichi nuclear disaster, one of the worst disasters in the history of nuclear power.
