基于GIS研究南黄海活动断层与地震的关系

基于GIS缓冲区分析和叠加分析的空间分析方法,定量研究南黄海活动断层与地震的关系.通过对震中与10 km和20 km断层缓冲区的叠加分析得出断层缓冲区内地震的数量,从中看出:走向NE～NEE向断裂是控制地震发生的主要活动断裂;通过对断层和震中缓冲区的叠加分析得出对地震发生有影响的断层的数量.

GIS-Based study on the Relationship between Earthquakes and Active Faults in the Southern Yellow Sea

Based earthquakes and on the buffer and active faults in the overlay methods of GIS spatial analysis, the relationship between Southern Yellow Sea is quantificationally studied. Statistics on the overlay analysis between earthquake epicenters and 10 kin, 20 km fault buffers gives the number of earthquakes for each buffer region, and shows that NW - NEE strike faults are the major earthquake-related active faults. Analysis on the overlay analysis between earthquake buffers and active faults gives the number of active faults that influences the occurrence of earthquake.
