南黄海地质及地震

南黄海属于华北地台及扬子准地台的一部分,是一个由隆起、拗陷组成的中、新生代大型复式盆地。海域内新构造运动以断裂、岩浆及差异性升、降活动为主,并且由现代活动断裂控制的地震频繁而活跃。南黄海的地震活动主要集中分布于南部拗陷与勿南沙隆起一带以及与江苏海岸相平行的浜岸断裂带上。今后较长时间内,南黄海的地震活动仍将沿着上述地带往复迁移

THE GEOLOGY AND SEISMICITY OF THE SOUTHERN HUANGHAI (YELLOW) SEA

The Southern Huanghai (Yellow) Sea is a part of the North China platform and Yangtze platform, and is a large Mesozoic and Cenozoic composite basin consisting of uplifts and depressions. In this area the neotectonic movement is dominated by faulting, magmatism and differential elevation and subsidence. There are frequent and active earthquakes resulted from recent active faulting. The seismic activity appears mainly in the southern depression-Wunansha uplift area and offshore fault zone parallel with the coast of Jiangsu. The seismicity will keep reciprocally migrating along the above zone within the corning longer period.
