Fig. 10From: Regional terrain-based VS30 prediction models for ChinaSpatial variation trends of the residuals and the updated VS30 prediction results in three regions. Spatial variation trends of the residuals obtained using the IDW interpolation method for: a the CM Region, c the CD Region, and e the GG Region. Final prediction models obtained by multiplying the initial prediction models by the residuals for: b the CM Region, d the CD Region, and f the GG RegionBack to article page
