Elastic full seismic waveform inversion of SAFOD data
This project aims at a seismic site characterization of the San-Andreas-Fault-Observatory-at-Depth (SAFOD) from controlled-source refraction- and reflection-seismic data using elastic Full Waveform Inversion (FWI). Previous studies based on acoustic FWI, travel-time tomography, and reflection Imaging provide detailed models down to 5 km depth but fail to resolve relevant details of the fault zone structure. Within this project we invert the seismic wave equation in 2D to obtain high-resolved P- and S-wave models. The project is funded by DFG within the ICDP special program.
