1 ∶250,000 regional seismotectonic map is one of graphic documents achieved in the urban active fault survey project.
1/25万区域地震构造图是城市活断层探测工作的成果图件之一。
The assessment of regional seismotectonic environment is very important for seismic safety evaluation of engineering sites, and it is essential to compile a regional seismotectonic map for the region where engineering site is.
利用西南地区多年来积累的地震安全性评价工作成果,借助地理信息系统MapInfo强大的空间信息表达能力,使在MapInfo平台上构建西南地区区域地震构造图数据库成为可能。
