一前言地震是一种地质现象,是地壳运动过程中所发生的一种运动形式。目前我们对地震地质的研究还很不够。在地震预报中,地震地质工作还多局限于对地质构造性质、晚期断层活动等方面的描述,从而提出地震发生的地质背景,以及划分地震区等。但地质背景的变化是很缓慢的。从地质背景不能显示出未来地震发生的时间。因些在地震预报中就不能起到应有的作用。为着更有效地作好地震预报,地震地质除研究一个地区的地质构造外,还应该注意到 An Introduction Earthquakes are a geological phenomenon that is a form of movement that occurs during the crustal movement. At present, our research on seismic geology is still not enough. In the earthquake prediction, the geology and geology work is still more limited to the description of the geological tectonics and the late fault activities, so as to propose the geological background of the earthquake and divide the earthquake area. But the change of geological background is very slow. From the geological background can not show the time of future earthquakes. Because of these in the earthquake prediction can not play its due role. In order to make the earthquake prediction more effective, the seismic geology should pay attention to the geological structure of a region
