Coastal effects of the 2011 Tohoku Tsunami along central Fukushima coast were investigated based on field survey and numerical calculation. The field survey was conducted in the central region of Fukushima coast with a 40 km stretch, where tsunami surveys were delayed due to the Fukushima Dai-Ichi nuclear power plant accident. Tsunami inundation and runup heights were measured using a VRS type RTK-GPS and laser rangefinders. Numerical tsunami calculation was performed with the model based on the linear long wave theory. The results revealed that the alongshore distribution of the tsunami height was dependent on the characteristics of tsunami source as well as the bathymetry at the depth greater than 200m. The inundation and runup heights appear to be highly influenced by the coastal and inland topography.
