Abstract
Followings are some characteristics of the influences of this tsunami along the Sanriku coast observed by the survey members : H. Naito, S. Nakagawa, S. Ogasawara, M. Kawakami, K. Yamashita, and H. Fukui. The damages by the Tsunami were very slight in the iandareas of the coast, while considerable destruction was given to oysters, lavers, Wakame and others which have recently developed in the bays along the coast. The arrival of the highest waves of the Tsunami in this coast coincided with the low tide, and the heights of the waves were smaller than at the time of the Chile Tsunami in 1960. The walls constructed for Tsunami deffence along the coast esinc the Chile Tsunami proved very effective to protect the settlements and arable land.
