Joint inversion of passive geophysical data

Overview & Synopsis

In this Thesis, I present a joint inversion framework using correspondence maps (CM) between surface-wave dispersion curves recovered from ambient seismic noise correlations and magnetotelluric data to solve for shear velocity and resistivity with depth, but at the same time for a possible relationship between them. The method is stable using synthetic and field data for 1D models and shows a reduction of the model space that fit all datasets simultaneously. A sensitivity study of surface-wave dispersion curves using 2D velocity models exposes some limitations on their lateral resolution for small-sized anomalies (
