초록

In this study, we applied the teleseismic receiver function technique to determine the crustal thicknesses and ratios for 31 broadband stations of the Korean Peninsula and map out the lateral variation of Moho depth in the Peninsula. The estimated depths to Moho range from 26 to 35 km except for an island station ULL (17 km). The Moho is turned out to be deeper in the south-western part of the Peninsula and western Gyeongsang basin, and shallower in the off-shore region close to East Sea (Sea of Japan). The ratio varies from 1.69 to 1.89 with the average of 1.77, which is close to global average (1.78) in the crust.
