摘要: Usually, seismic record stations are established in various topographic slope positions, from valleys to ridges. In most previous studies, amplification factor (TAF) is proposed as one of the indicators earthquake wave which can lead overestimation magnitudes networks. This paper uses an indicator called “Topographic Position Index” for characterization Hokuriku region, Japan, and deals with a individuation method through Voronoi tessellation, spatial approach, propose suitable sites topographically unbiased or less-biased stations.
