P and S Wave Velocity Structure of the Crust and Upper Mantle Under China and Surrounding Areas From Body and Surface Wave Tomography

摘要: Abstract : We have used a combination of travel-time and surface wave tomography to obtain compressional shear velocity distributions in the crust upper mantle under China surrounding areas. first determined 3-D P- S-wave structures for uppermost using local regional arrival time data. Travel-time data from Annual Bulletin Chinese Earthquakes (ABCE) International Seismological Centre (ISC/EHB) were used. then extended model deeper into through transition zone ISC/EHB P PP phases combined with ABCE also broadband stations determine S-velocity structure. Multi-mode was employed whole region areas ambient noise interferometry Tibet.
