【摘要】 建立基于有限断层的汶川8.0级地震的混合震源模型。其中,全局参数主要根据区域地震构造、地壳结构、地震活动性和半经验标定公式估计。局部参数分两组,一组是描述凹凸体的,另一组是k平方模型参数,依标定公式估算均值和标准差,由截断的正态分布生成。该文展示了构造的30个震源模型。更多还原

【Abstract】 A finite fault based hybrid source model of the great Wenchuan earthquake with magnitude 8. 0 is built in this paper. The global parameters are mainly determined from the regional seismo-tectonics,structure of the crust,seismicity and a set of semi-experiential calibration laws. The local parameters consist of two groups. One is on asperity,the other one is on k square distribution. Both of them are generated from the truncated Normal distribution with mean and standard deviation values estimated by a set of calibration laws. 30 source models are presented finally.更多还原
