将福建省面积按0.05°（约5 km）网格离散化后得到4 361个网格点,在地震发生后根据全省台站的监测数据进行计算,每个网格点都能快速得到地震动峰值加速度。利用这些已经赋有地理信息和加速度的网格点对全省乡镇级单位的行政区进行烈度计算和赋值提出一种基于地震动峰值加速度的地震灾害评估方法。%The area of Fujian province is divided into 4 361 grid points with geographic information and the acceleration by 0.05° degree（about 5 km） grid discretion,and every grid point can quickly get the peak acceleration of ground motion after earthquake,and the method of earthquake hazard estimation is given based on peak acceleration of ground motion.
