Enhancing Crustal Velocity Structure in Sedimentary Basin by joint inversion of Teleseismic P-Wave Reverberations and Surface Wave Dispersion

Abstract

Accurately determining the crustal velocity structure within sedimentary basins is crucial for enhancing energy resource evaluation and seismic hazard assessment. Traditional crustal imaging is challenging due to the interference of teleseismic P-wave reverberations (TPR). To address this issue, we propose an inversion strategy that combines multi-frequency TPR and surface wave dispersion (SWD) to constrain the crustal structure. Both theoretical simulations and real data tests from two stations in the Songliao Basin validate our approach. This method shows great promise for improving crustal structure investigations in complex environments, such as sedimentary basins and oceanic regions.
