Lack of efficient preparation---Okawa Elementary School

The earthquake that struck Japan on Friday 11 March 2011 was the fourth most powerful in the history of seismology. It knocked the Earth six and a half inches off its axis; it moved Japan four metres closer to America. In the tsunami that followed, more than 18,000 people were killed. At its peak, the water was 40 metres high. Half a million people were driven out of their homes. Three reactors in the Fukushima Daiichi power station melted down, spilling their radioactivity across the countryside, the world’s worst nuclear accident since Chernobyl. The earthquake and tsunami caused more than $210bn of damage, making it the most costly natural disaster ever.
