Abstract

This study highlights erosion of sandy coasts and river mouths in Miyagi Prefecture due to The 2011 Great East Japan Earthquake Tsunami, based on a field investigation and aerial photograph analysis. Mechanism of beach erosion due to the tsunami is classified into three types considering geological formation and coastal structures. Furthermore, complete flushing of sand spit and severe breaching of coastal barrier are observed at several river entrances, which is one of the distinct differences as compared with tsunami disasters caused by The 2010 Great Chilean Earthquake Tsunami. The findings of this study may be useful for preparing for tsunami disaster prevention and preparedness in Japan.
