华东沿海地震海啸模拟
|
摘要
利用数字地震资料及海洋地震地质基础数据,基于Matlab平台在Windows系统下重新编译Philip liu等人编写的海啸模拟源程序,将分层静态位移解结果与已建立的海啸传播初始场快速融合,用交错网格蛙跳差分方法求解笛卡尔坐标系下非线性浅水波方程,模拟华东沿海地区地震海啸传播过程,对华东沿海地区可能遭受海啸袭击的危险做出评估,结果显示华东沿海地区是发生地震海啸影响较弱地区。
Based on comprehensive consideration of topography,geological structure,seismological features and historical records,we simulated an earthquake tsunami with the rebuilt program from Prof.Philip Liu based on Matlab and Windows OS.We used crossed grid leap-frog difference scheme to solve linear or un-linear water wave functions in spherical coordinate and rectangular coordinate system,and simulated a scenario earthquake tsunami propagation in the coast area of East China,and evaluated the risk and hazards for the area.The results show that the coast of East China is lowly influenced by earthquake tsunami.
