【摘要】 利用马尔康台记录的数字地震波资料,使用波谱分析方法计算了马尔康地震序列93次ML2.5～5.0地震的震源参数,并对其进行了初步分析。结果表明:马尔康地震序列的地震距(M0)与震级(ML)有较好的相关性,关系式为log10M0=0.92ML+10.24,相关系数R为0.86;地震应力降与震级的关系不明显,二者基本无关。更多还原

【Abstract】 Using digital wave data recorded by the Ma’erkang station,source parameter for 93 earthquakes with M _L 2.5～5.0 of the Ma’erkang area are determined by spectral analysis.Preliminary analysis of the source parameter show that there is a high correlation between seismic moment M ₀ and local scale M _L,which is log 10M ₀=0.92M _L+10 ^24,correlation coefficient R is 0.87;The relationship of stress drop versus local scale M _L indicates that the stress drop seems independent of M _L.更多还原
