The Detection of the Low Velocity Body Using Seismic Waves

Abstract

low velocity body was detected during the investigation of the crustal structure and upper mantle in the Korean I'eninsula using ray method and observational seismic data. observed the arrival time delays of I' and waves that pass through the hot spring area and the Chugaryong rift zone in the Korean Peninsula. The present geothermal exploration accounts for the high heat flow in these regions, suggesting that the area are the delay shadows' produced by a deep, low velocity el al., 1980). We tried to verify the hypothesis that the low-velocity body is caused by the partial melting in the lower crust can be explained by the lateral model) of the lower crust using Hay Method.
