Geophysical imaging has traditionally provided qualitative information about geologic
structure; however, there is increasing interest in using petrophysical models to convert …

This book describes the theory and practice of inverting seismic data for the subsurface rock
properties of the earth. The primary application is for inverting reflection and/or transmission …

We determine the effect of replacing geometrical ray theory in surface wave tomography with
scattering theory. We describe a tomographic method based on a simplified version of the …

We develop a waveform-tomography method for estimating the velocity distribution that
minimizes the waveform misfit between the predicted and observed early arrivals in space …

This efficient multiscale method for time-domain waveform tomography incorporates filters
that are more efficient than Hamming-window filters. A strategy for choosing optimal …

Surface-based ground penetrating radar (GPR) and electrical resistance tomography (ERT)
are common tools for aquifer characterization, because both methods provide data that are …

Cross‐hole radar tomography is a useful tool for mapping shallow subsurface electrical
properties viz. dielectric permittivity and electrical conductivity. Common practice is to invert …

The mapping of variations in P wave speed in the deep mantle is restricted by the uneven
sampling of P waves, in particular beneath the Southern Hemisphere. To enhance data …

A three‐stage inversion technique for surface wave tomography is applied to the Australian
region. The inversion procedure consists of three independent processes. In the first stage …
