Effect of Tsunami Evacuation Buildings and Seawalls using the Tsunami Evacuation Simulator in Iquique, Chile

摘要

After The 2011 off the Pacific coast of Tohoku Earthquake, it has become important that not only enhancement of hardware side e.g. construction of seawalls, but devising the comprehensive effective disaster prevention schemes including software measures like establishment of evacuation scheme, according to increase of possible tsunami height. Arikawa and Oie(2015) developed the evacuation simulator coupled with numerical wave flumes STOC(Tomita et.al. 2006) or CADMAS/3D(Arikawa et.al. 2005). They discussed how evacuation behavior is effected by evacuation place. In this study, using this model, the effect of the installation of tsunami evacuation building and seawalls, and the height of the seawalls on evacuation behavior is discussed.
