History

Historical Context

On 11 March 2011 the Japan Meteorological Agency recorded a magnitude 9.1 Tohoku quake that triggered a tsunami and the Fukushima Daiichi nuclear disaster, leaving over 300,000 homes without power and causing more than $300 billion in damage. A subsequent 5.9-magnitude Ibaraki tremor led the Crisis Management Center to act and University of Tokyo professor Shinichi Sakai to warn of landslides, prompting stronger infrastructure and warning systems.
