The “Kriging difference analysis” method was used to draw the annual variation contour of groundwater depth, variation zone, variation zone, county and water supply degree zones superposed and intersecting. The “water level (buried depth) variation method” was used through field computer. Calculate the groundwater storage variable of the cell plot. The methods and detailed operation steps of ArcGIS 10.8, such as drawing variable contour, variable partition, intersection, field calculator and calculating variable storage, are described.展开更多

Investigating seismic focus rupture information using D_InSAR is a scientific issue to which more attention is being paid. In this paper, the basic theory of seismic focus dislocation models is discussed briefly. Based on a map of the interferometric deformation field of the Zhangbei_Shangyi earthquake from Jan.10, 1998, and applying the seismic focus dislocation model within elastic half_space medium; some geometrical and kinematical characteristics of the main seismic fault are deduced. Results were as follows: the seismic break surface of the Zhangbei_Shangyi earthquake is left_slip and thrust fault, striking in SEE_NWW 272°with dip angle 46°; rupture direction is unilateral faulting from SEE to NWW; length of rupture zone is 9km, width is 8km, and depth is 8km, the displacement vector of three directions are 290mm, 560mm and 0mm.展开更多
