Progress of Joint Inversion of Geodetic and Seismological Data for Seismic Source Rupture Process

  • 摘要: 综述了近10多年来大地测量和地震数据联合反演地震震源破裂过程的研究成果及最新进展,特别是大地测量和地震数据联合反演地震震源破裂过程的模型、算法及典型震例。展望了利用GPSI、nSAR和地震波数据联合反演震源破裂过程中顾及先验信息、附有不等式约束时反演模型的建立方法,以及相对权比的确定、全局优化方法的应用等问题。

     

    Abstract: The achievement and new progress in joint inversion of geodetic and seismological data for seismic source rupture process in the recent decade are summarized in this paper.The models,algorithms and typical earthquake cases in joint inversion of geodetic and seismological data for seismic source rupture process are discussed.The establishment of joint inversion model with GPS,InSAR and seismological data considering prior information and with inequality constraints is discussed.The functions of various data,determination of relative weight ratio and application of global optimization algorithm are emphatically discussed.
