海啸易损性（易损性曲线，或易损性函数）是一种新的评估海啸结构破坏和人员伤亡的方法，它将卫星遥感、现场调查、数值模拟和历史数据分析与地理信息系统（GIS）相结合。海啸脆弱性是指与海啸淹没流的水动力特征（如淹没深度、流速和水动力）相关的结构破坏概率或死亡率。它扩大了以定量方式估计潜在海啸损害的能力。
Tsunami fragility (fragility curve, or fragility function) is a new measure, we propose, for estimating structural damage and fatalities due to tsunami attack, by integrating satellite remote sensing, field survey, numerical modeling, and historical data analysis with geographic information system (GIS). Tsunami fragility is expressed as the structural damage probability or fatality ratio related to hydrodynamic features of tsunami inundation flow, such as inundation depth, current velocity and hydrodynamic force. It expands the capability of estimating potential tsunami damage in a quantitative manner.
