ABSTRACT
The 2011 Great East Japan earthquake (i.e. Off Pacific Coast of Tohoku Region, Japan earthquake) with the magnitude of 9.0 occurred at 2:46 p.m. (local time) on March 11, 2011. The fault zone extended 450 km and 200 km in the north-south and west-east directions, respectively (Kawashima 2012). The 2011 Great East Japan earthquake caused multiple disasters, including the damage and collapse of structures and infrastructures due to strong ground motions and/or liquefaction, the washout of structures and infrastructures due to the subsequent tsunami, fires, landslides, and the subsequent radiation crisis.
