Research I am working with Dr Yehuda Ben-Zion on rupture process within the fault zone. Currently we combine various methods to get the spatial-temporal distribution of rupture velocity. We are also interested in imaging the fault zone structure based on scattered wavefield. M.S. thesis: Appraising the Reliability of Scattered Seismic Wavefield Imaging. Keywords: 3D imaging, error appraisal, Born Approximation, point scatterers. • This is a project to appraise the reliability of scattered P-to-S wavefield imaging and study the nature of 410 km mantle discontinuity and subducted slab. • We have implemented a program which calculates synthetic seismic data for point scatterers in radially symmetric models. Then the synthetic data are loaded into the imaging program to generate a 3D imaging volume which contains the model reconstruction.
