What is the Tohoku Japan case study of 2011?

On the 11th of March, 2011, at 2;47 PM, an earthquake with a magnitude of 90 mW shook north-east Japan, triggering a tsunami in the Pacific region. The Pacific plate which moves 83 mm a year was thrust under the Eurasian plate at the Japan Trench. Faulting occurred 300 km along the trench causing an upward fault at 10 meters, and a sideways at 50 meters. The focus was around 30 km below the seabed and the epicentre was 130 km east of Sendai. Primary impacts were 667-1,479 deaths directly due to the earthquake, no electricity and land subslides. Secondary impacts were economic costs, high radiation levels and liquefaction.
