VP/VS ratios in the upper crust of the southern Korean Peninsula and their correlations with seismic and geophysical properties

► VP/VS ratios in the upper crust of the southern Korean Peninsula, the far-eastern margin of Eurasian plate. ► Spatial correlation between VP/VS ratios and tectonic structures. ► Comparisons of VP/VS ratios with various geophysical and seismic estimates. ► Inference of crustal structures and their connection to the mantle lid.
