The north coast area of Iwate Prefecture was attacked by Tunami due to the 2011 Off The Pacific Coast of Tohoku Earthquake. This study mainly surveyed the tunami wave vestige in the coast area of Iwate Prefecture. Firstly, this study surveyed the heights from sea surface to the top of the wave vestige, there are remained on the wall of the house and on the ground slope due to wave run up. Secondary, the observed values are changed to the height of the Tokyo datum line by the tide prediction model.
In results, the heights in this area are about 17m to 20m. However the wave increased over 30m due to the wave interference in the middle area of Noda Bay. In the many bay, example for Miyako Bay, the wave heights decreased at the inner area. However the heights increased in Hirota Bay.
