摘要
以MAPGIS软件为基础平台 ,利用GIS缓冲区分析和空间叠加分析技术 ,研究上海及邻近海域地震与活动断裂的关系。研究区地震活动断裂的发育程度以继承性NE -NNE向为主 ,但其活动强度不及NW -NNW向及近EW向断裂 ;沿NW -NNW向及近EW向断裂两侧 ,中强地震发生频率明显高于NE -NNE向断裂 ;不同时代活动断裂与中强地震之间存在一定的联系 ,表现为随着断裂活动时代变新 ,断裂周围中强地震发生的频率升高。
The relation between earthquakes and active faults in Shanghai and its adjacent offshore region was quantitatively evaluated using GIS-based buffer and overlay analysis techniques. Statistics on the distance from the epicenter of an earthquake to its nearest active fault suggest that most earthquakes in the study area occurred within 10 to 20 km of major active faults. The strikes of active faults have significant influences on the occurrence of earthquakes. The NE-NNE-striked faults are less active than NW-NNW- or EW-striked faults. Along the NW-NNW- or EW-striked faults, the frequency of earthquakes is much higher than that along NE-NNE-striked faults. The time of fault activity has some degree of influence on the earthquakes. The newer the faults, the higher the frequency of earthquakes within the zone of the faults.
