地震学家对遥感图象上的线性构造带和网络状构造格局及其与地震的关系很感兴趣,但对环形构造——遥感图象一种比较特殊的构造形态及其与地震的关系并没有引起足够的重视。多年来,笔者利用遥感图象初步分析了我国西北地区的地震构造环境,本文就环形构造在地震研究中的作用,谈几点认识。 Seismologists are very interested in the linear tectonic belts and network tectonics on the remote sensing images and their relationship with earthquakes. However, for ring structure-remote sensing images, a rather special tectonic shape and its relationship with earthquakes Did not cause enough attention. Over the years, the author has made preliminary analysis of the seismic tectonic environment in the northwestern region of China by using remote sensing images. In this paper, the role of annular structures in earthquake research is discussed.
