| 摘 要： | 为建立中国西部走滑型活动断裂的滑动速率、破裂参数与震级之间的经验关系,系统搜集和整理了中国西部地区30个大地震的震级以及发震断裂(段)的活动参数和破裂参数资料,包括断裂(段)长度、滑动速率、最大位错等及其不确定性.为考虑各种参数的不确定性,采用蒙特卡罗( MonteCarlo)方法,对各种参数进行最小二乘法回归分析,给...

| Abstract: | In this paper,the relevant faulting and rupture-scale parameters of 30 large earthquakes were systematically collected and compiled,including fault length,slip rate,magnitude and their uncertainties.Considering the uncertainties of these parameters,10000 Monte Carlo realizations were generated consistent with the ranges of data,and for each a standard least-squares technique was used to find the coefficients of regressions.A comparative analysis with previous empirical relationships of the same type suggest... |
