| 摘 要： | 经对1947年青海达日73/4级地震区多时相航空、航天遥感资料研究发现：该区北西西向线性构造对达日73/4地震起主导作用,另外在经增强处理的陆地卫星图像上也反映出达日县桑日麻盆地存在近东西向隐伏断裂,结合航磁资料分析,平顶山环形影像是一巨大隐伏岩体的反映。据此推断的达日地震构造,较好地解释了孕震过程,为确定宏观震中提供了依据。

| Abstract: | Throng the studies on the seismic region (ML=73/4) shaking in 1947 at Dart Qinghai with the multitemporal aerospace remote sensing data, It was showed that the NWWlinear structure in the area played a dominant role in Dari’s earthquake, and the near EWblind fault appeares on the enhanced Landsat image of Sang Rima basin, Dart, and the ring image of Pingding mountain was considered to be a huge concealed rock mass with the aid of the aeromagnetic surveying data. According to the Dari’s seismic structure inferred, the seismic process can be explained well, and the basis for determining macroscope epicentre was provided. |
