摘要
选取苏南地区(30°~35°N,115°~125°E)为研究区,采用中国地震局提供的1970年以来ML≥2.0级地震活动的资料,经过完整性和一致性处理,对研究区进行全时空扫描确定中短期预备空区,以分析该地区中强地震前地震活动性图像的时间、空间及强度演化特征。
The south area(30°~35° N,115°~125° E) of Jiangsu province is chosen as the studied region,and the characteristics of seismicity pattern evolution before medium-strong earthquakes in this area are studied by the earthquake activity data of ML≥ 2.0 since 1970,which were scanned by time and space and determined the middle and short term gaps.
