摘要
利用时间城小地震地震图的方法,研究了震源参数与介质特性的差异。据初步研究结果,伊通-舒兰断裂南、北两段的震源应力降与Q值存在差异。该方法是断层的震源深度范围内介质特性研究的补充,为断裂的分段提供一个重要方法。
In this paper,the difference of earthquake source parameters and medium property has been studied,by using small earthquake maps within a time domain.The preliminary study result shows that the two segments in question show differential source stress drop and Q value,which can be explained by the earthquake activity.This method is a supplement of the study of fault within the depths of earthquake source,and provides an important means for fault segmentation.
