Abstract
Characteristics of the 2011 Tohoku Earthquake tsunami and resultant damage on the coast of Tokyo Bay were studied using a field survey, an analysis of observed tsunami wave profiles and numerical hindcasting using FVCOM. The tsunami was found to overflow in several fishery ports, leading to unexpectedly high inundation and runup heights of 2.84 m and 2.91 m in Funabashi Fishery Port and Shin-Futtsu Fishery Port, respectively. The observed tsunami wave profiles indicated that the tsunami wave entered the bay with a period and a maximum height of approximately 60 min and 0.9 m, respectively, and propagated along the major axis with nearly uniform height, while the wave was amplified in ports, which characteristics were successfully reproduced by numerical hindcasting.
