MASW is a common processing method for civil/geotechnical and even for oil/gas exploration (usually weathering static corrections) applications. In my experience, it seems to work well for most environments and various subsurface conditions.
The more I learn about FWI and MASW (for either Raleigh- or Love-waves), the more I realize that perhaps one day FWI methods will surpass any MASW processing because it attempts to overcome the limitations naturally imposed by MASW because of its inherent assumptions of subsurface conditions.
To date, I cannot find a case study that compares both methods in a single environment. Also, I realize that deriving a reliable source function, recording the 3-D seismic wavefield, and overcoming the stability constraints associated with multiparameterization of FWI (especially for elastic wave phenomenon) is task to be handled with in the future.
My questions are: (1) Has anyone seen a paper dealing with comparing both methods - if so, where? (2) Will some form of FWI possibly surpass MASW workflows (e.g. ParkSeis or SurfSeis) in the near future?
