The Tsunami triggered by the 2011 off the pacific coast of Tohoku Earthquake resulted in huge damage to infrastructures in Tohoku and Kanto area of eastern Japan. This paper is a summary of the investigation related to the geotechnical disaster brought by the earthquake and the associated tsunami in the Aomori prefecture and northern areas of the Iwate prefecture. In the investigated area, rather than the earthquake itself, the disaster was compound (e.g. tsunami related geo-disaster and/or liquefaction related hazard, etc). The paper specially focuses on the disaster brought to the waterfront structures along the coastal area considering the effect of the earthquake and its intensity, the leading wave as well as the backrush of the tsunami, and the structural form, etc.
