摘要
应用中—法数字化地震台网自 1996年以来所记录到的微震S -P资料 ,对祁连山中东段地区三维速度结构与震源参数进行了联合反演 ,获得了该区的三维速度成像 .速度结果反映出深部构造的一些重要信息 ,为进一步研究该区的活动构造及地震参数计算 ,提供了科学依据 .
The 3 D velocity tomography image of the central eastern part of Qilian shan is obtained by the joint inversion of 3 D velocity structure and focal parameters based on the S P data of micro earthquakes recorded by the digital seismic network of a Sino French cooperation program since 1996. The inversed velocity structure does primarily reflect some important features of the deep structure in the region and provides the scientific background for the further study of active tectonic structure and the calculation of earthquake parameters.
