Shear wave velocity model beneath CBJI station West Java']Java, Indonesia from joint inversion of teleseismic receiver functions and surface wave dispersion

Earthquake signal observations around the world allow seismologists to obtain the information of internal structure of the Earth especially the Earth's crust. In this study, we used joint inversion of receiver functions and surface wave group velocities to investigate crustal structure beneath CBJI station in West Java, Indonesia. Receiver function were calculated from earthquakes with magnitude more than 5 and at distance 30 degrees-90 degrees. Surface wave group velocities were calculated using frequency time analysis from earthquakes at distance of 30 degrees-40 degrees. We inverted shear wave velocity model beneath the station by conducting joint inversion from receiver functions and surface wave dispersions. We suggest that the crustal thickness beneath CBJI station, West Java, Indonesia is about 35 km.
