From: Unified approach for evaluation of horizontal site amplification factors with special reference to history of studies on the effects of surface geology on seismic motion

Fig. 6

Comparisons of the empirical site amplification factors: a HSAF of the surface sensors relative to the seismological bedrock (HSAF_surface), b HSAF of the borehole sensors to the seismological bedrock (HSAF_borehole), and c the ratio between them (SBR), at 16 KiK-net sites in Aomori Prefecture and the overall geometrical means of all the 696 sites used (red broken lines)
