Abstract
The 2011 off the Pacific coast of Tohoku Earthquake (March 11; M = 9.0) triggered a large-scale tsunami, which struck the coast of northeast Japan. Subsequent surges accumulate voluminous seawater in front of the constructs. The increase of mass of seawater led to the destruction of the constructs. The first wave of tsunami hit and destroy the breakwater. Coasts without breakwater were inundated directly by the tsunami run-up. Energetic currents reworked smashed materials and transport them toward inland. The inundation was not attended with surface erosion, and left a thin sand layer covering the inland.
