| Abstract: | Based on 24904 P-wave arrival time data from 1132 events recorded at 140 stations in two seismic profiles across Tianshan mountain and in Xinjiang regional seismic network,tomographic images of P-wave velocity are achieved beneath Tianshan--Junggar region by travel time inversion.Result of checkboard tests indicates that the reliability of velocity perturbation recovering is relatively high for the region beneath the two profiles themselves,along Tiansh-an and eastern Junggar.The inversion result of P-wave ... |
