EEFIT report: The Tohoku earthquake and Tsunami of 11th March 2011


On 11 March the north eastern coast of Japan was hit by an 8.9 magnitude earthquake and tsunami. The event captivated audiences worldwide as the devastating effect to Japan’s infrastructure unravelled – not least the damage sustained to the Fukushima nuclear plant which prevented cooling of its reactors.

A mission team of nine, led by Antonios Pomonis and deputy leader Dr Keiko Saito, and included IRDR Director, Professor Peter Sammonds, was dispatched on 29 May to spend five days in Japan’s Tohoku region. The mission team carried out extensive investigations in the area – surveying ground motion and tsunami damage alongside geotechnical issues. The team also met with city officials in the region, looked at disaster and recovery management plans and the overall effect of the earthquake on the energy sector.

The findings of the team can be downloaded in the form of the EEFIT mission report

The EEFIT mission team also presented their findings at an evening technical meeting on Thursday 14 July 2011. The video recording from the event - EEFIT Technical Evening Meeting: Lessons from the Mw9 Great East Japan Earthquake and Tsunami of 11 March 2011 - can be viewed online.
