Abstract

The devastating 11 March 2011 magnitude 9.1 earthquake along the Tohoku coast of northeastern Japan reminded seismologists again of the adage, "It ain't what you don't know that gets you into troubleit's what you know for sure that just ain't so." Many seismologistsand hence disaster plannersthought that such huge earthquakes could not occur on this subduction zone [Chang, 2011; Geller, 2011]. Great earthquakesmagnitude 8were expected and planned for. However, a giant magnitude 9 earthquake, which would release 30 times more energy, was not considered.
