报告内容摘要 :
The recent vast deployment of linear seismic arrays all around the world, especially in China, provides a good opportunity to conduct full waveform inversion investigations with the SEM-FK hybrid method. The socalled full waveform inversion (FWI) is the last course of data analysis in seismology and has been widely explored during the last decade. However, the application of FWI into real data is computationally expensive. To make the powerful and promising FWI computationally feasible, in this talk I will present the SEM-FK hybrid method for the numerical modelling of teleseismic incidence with local heterogeneities. Synthetic tests for proof of concept will be discussed. Vice versa, the SEM-FK hybrid method will be the necessary tool for imaging the detailed subsurface structures beneath the newly deployed seismic arrays.
