Spatial interpolation of H/V spectrum of microtremor by external drift kriging


Abstract
The authors carried out microtremor observation in order to investigate the spectrum amplification of ground in fill and cut land in reclamation. It was found that it was possible to investigate the characteristics of the spectrum amplification in fill and cut land by microtremor. However, if it is trying to understand the ground amplification in fill and cut land, it is required a spatial interpolation method relation to the spatial distribution of fill and cut land. Then, we applied an external drift kriging method considering relative height of the elevation of old topographic maps and current topographic maps. As a result, we obtained the spatial distribution of the H / V spectrum captures the shape of valley in the old topographical maps.
