Abstract

The receiver function (RF) method has been widely applied to estimate velocity structures of Earth’s crust and mantle using teleseismic data. In this study, we perform a RF iterative deconvolution method to detect the depth variations of seismic bedrock in the Taipei basin and Chiayi area. We use strong motion data recorded by five and seven stations in the Taipei basin and Chiayi area, respectively. The Ps–P times appear at about 0.235–0.93 s for the Taipei basin and 1.015–1.685 s for the Chiayi area. The time differences imply gradually increases of the bedrock depth from southeast to northwest in the Taipei basin and from east to west in the Chiayi area. Our results show that the method can efficiently detect depth variations of seismic bedrock which are consistent with those from other geophysical observations as well.
