摘要
中强地震构造标志研究是一项很重要的基础研究,它对认识地震成因、进行地震预报和开展工程地震等都是非常重要的。通过多次野外调查和大量资料分析,我们认为下扬子及部分邻区中强地震构造标志主要有以下5点,即新构造差异带、断陷陡深带、活动断裂带、构造分水岭和地貌断阶带。
The research on the seismotectonic marks of moderate strong earthquakes is a kind of foundamental study work. It is very importune to genesis of earthquake, earthquake prediction, and earthquake engineering. Based on field investigation and comprehensive analysis, the present authors recognized five seismotectonic marks of moderate strong earthquakes in Lower Yangtze region and partial adjacent areas, i. e.
1. differential zone of neotectonie movement; 2. zone where the faultdepresion basin is very deep; 3. active fault zone; 4. tectonic watershed; 5. geomorphologic fault-step zone.
