Some specific legends and traces related with historical tsunamis have been handed down among the people in the northern part of Honshu, Japan. Examples are the forest of Hiba buried by a large amount of sand and the resettlement of villages damaged by tsunamis in Shimokita Peninsula, the northeast Honshu. The aim of this paper is to reexamine their reliability by compiling old documents and results from numerical simulation of tsunamis. Results from old documents combined with numerical simulation suggest that the legends at the age of Tensho and Kan-ei period would be associated with not tsunamis but floods. And the story of damage at Tanabu town by the 1611 Keicho tsunami causing resettlement to a higher place is not reliable because the simulated tsunami could not reach the locations of the village. The sequence of events of sand transport to bury Hiba forest at four different ages could be found by filed investigation and result of dating of 14C. The ages do not correspond to the tsunami events. Such process can be explained by a formation of sand dune, meaning that a large amount of sand movement should not be caused by tsunamis.

@hikawamomo いや青森には東北方面隊隷下の第9師団第9化学防護隊っていう特殊任務を担う専門家部隊も駐屯しているから(当然ですよね、八か所村があるわけで)、最適地だと思うんですよ。それに歴史的に見ても津波被害少ないんです。https://t.co/VYc3SVb9Nb
