On 11 March 2011 a megathrust earthquake (M 9.0)—the largest recorded earthquake in the history of Japan—occurred off the Pacific coast of Tohoku-oki (Table 1). The earthquake ruptured the interplate boundary offshore of northeastern Honshu with several earthquake rupture models suggesting peak epicentral displacements up to 30–40 m and duration about 150 s. Several focal mechanism estimates (e.g., the weighted cumulative moment tensor [WCMT] with slab geometry from U.S. Geological Survey;
