Today, surface-wave analysis is widely adopted for building near-surface S-wave velocity
models. The surface-wave method is under continuous and rapid evolution, also thanks to …

The goal of this paper is to provide an overview of the current state of the art in seismic
tomography, and trace its origins from pioneering work in the early 1970s to its present …

Ambient noise tomography is a rapidly emerging field of seismological research. This paper
presents the current status of ambient noise data processing as it has developed over the …

We present the first-generation global tomographic model constructed based on adjoint
tomography, an iterative full-waveform inversion technique. Synthetic seismograms were …

We propose a method to invert surface wave dispersion data directly for 3-D variations of
shear wave speed, that is, without the intermediate step of phase or group velocity maps …

Resolution in seismic tomography intimately depends on data coverage, with different parts
of seismograms sensitive to different parts of Earth's structure. In classical seismic …

We present a new global model for the Earth's crust based on seismic refraction data
published in the period 1948–1995 and a detailed compilation of ice and sediment …

We describe a method to invert surface wave dispersion data for a model of shear velocities
with uncertainties in the crust and uppermost mantle. The inversion is a multistep process …

We describe a method to invert regional or global scale surface-wave group or phase-
velocity measurements to estimate 2-D models of the distribution and strength of isotropic …

We present a method that uses a global seismic model of the crust and upper mantle to
guide the extrapolation of existing heat-flow measurements to regions where such …
