The proposal is based on the GIS of surface topography, aerial photographs, satellite imagery, GIS maps of the Geotektonischer Atlas and mapping of penetration points of near surface already achieved in project SI 594/14-1; SI 594/14-2. It is the objective of this study to quantify the movement-rates of active faults during the Holocene, Pleistocene and Tertiary and depict the causes and mechanisms of active movements in the upper crust in SH. We selected 6 working areas from the existing map of Bewegungspotentiale . A seismic survey of the uppermost 200 m will be done by 50 lines of 250 m length (altogehter 12,5 km) to detect the exact position, inclination and slip rate of the near surface faults. We will combine the GIS analysis of 190 layers (from modern hydrography to Base of the Permian) with the results from the seismic survey and quantify the role of isostatic adjustment, diapirism, compaction and active tectonic forces in the NW German basin. Based on the understanding of the processes of recent upper crust movements we will calculate the movement rates for the next 20 years, which can serve as basis for planning of pipeline tracks, dike stability, road- and building construction.

该提案的依据是地表地形地理信息系统、航空照片、卫星图像、Geotektonischer Atlas的地理信息系统地图以及项目SI 594/14-1和SI 594/14-2中已经完成的近地表穿透点绘图。本文旨在定量研究上海地区全新世、更新世和第三纪活动断裂的活动速率，并揭示上海地区上地壳活动的原因和机制。我们从Bewegungspotentiale的现有地图中选择了6个工作区。将通过50条250 m长的测线（共12.5 km）对最高200 m进行地震勘测，以检测近地表断层的准确位置、倾角和滑动速率。我们将190层（从现代水文到二叠纪底）的GIS分析与地震调查的结果相结合，并量化德国西北部盆地的均衡调整，底辟作用，压实作用和活动构造力的作用。基于对近期地壳运动过程的了解，我们将计算未来20年的运动速率，这可以作为规划管道轨道、堤坝稳定性、道路和建筑物建设的基础。
