The main objectives of the project are

• Study the sensitivity of different types of waves to some elastic changes, both in terms of both kinematics (time delays) and dynamics (amplitude modifications);

• Propose a strategy to map the changes (recorded by the waves at the surface in the time domain) to some subsurface locations (i.e. construct partial images to locate the changes in depth);

• Assess uncertainties (Bayesian context) on the modifications of the subsurface images by considering different sources of uncertainties, while respecting a priori information;
