Abstract

Using the microearthquake data acquired from 1995 to 1996 through the seismic network operated by the Korea Institute of Geology, Mining & Materials (KIGAM), the three P-wave velocity models proposed by Lee (1979), Kim·Kim (1983) and Kim·Jung (1985) concerning the structure of the southeastern part of the Korean peninsula were examined in terms of the least square errors of the P-wave arrival times. The three models do not differ significantly in arrival time residuals except that the Lee's model gives slightly deeper focuses than the others. The layering of the crust of the peninsula is not clear as yet and to be studied by more earthquake and explosion data in the future.
