根据GPS和InSAR数据反演2001年昆仑山口西地震同震破裂分布
昆仑山口西地震 破裂分布 大地测量资料
font style='font-size:12px;'>
2009/4/27
2001年昆仑山口西地震经历了一个相当复杂的破裂过程，迄今为止用不同资料、不同方法和模型得到的同震破裂发布具有很大差异.我们采用地震前后GPS和InSAR观测数据得到的同震位移反演该地震的同震破裂分布，检验各种可能的模型参数，得到在数据与平滑优化约束下尽可能详尽的结果.建模过程经历三个步骤：（1）采用直立断层模型反演，根据解的分辨率和拟合差的折中曲线得到最优平滑约束；（2）改变断层倾角，找到使得观...
从全球长周期波形资料反演2001年11月14日昆仑山口地震时空破裂过程
长周期波形资料 时空破裂过程 破裂的聚合
