Developing Tsunami Fragility Curves Due to the 2009 Tsunami Disaster in American Samoa

Abstract

The authors developed the tsunami fragility curves due to 2009 samoa earthquake tsunami, to investigate structural vulnerability in the affected area, by integrating satellite remote sensing, field survey, numerical modeling, and GIS analysis. In this paper, the authors propose three kind of tsunami fragility curves of structural destruction with regard to the inundation depth, current velocity, and hydrodynamic force.
