Ambient noise multimode surface wave tomography

open access: yesProgress in Earth and Planetary Science
Seismic techniques using earthquakes are powerful tools for exploring the Earth’s internal structure. However, the earthquake distribution limits the spatial resolution.

Advances in surface-wave tomography for near-surface applications

open access: yesThe Leading Edge, 2021
Abstract Surface-wave (SW) tomography is a technique that has been widely used in the field of seismology. It can provide higher resolution relative to the classical multichannel SW processing and inversion schemes that are usually adopted for near-surface applications.

Global surface wave diffraction tomography [PDF]

open access: yesJournal of Geophysical Research, 2002
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 scattering sensitivity kernels that emerge from the Born or Rytov approximations in which surface wave travel times are a weighted average of phase or group slowness over ...

Study on surface-wave tomography in Abaga volcanic area, Inner Mongolia

open access: yesFrontiers in Earth Science, 2023
In this paper, the 3-D S-wave velocity structure of the crust and upper mantle in the Abaga volcanic area of Inner Mongolia was inverted by using the surface-wave tomography method, with a resolution of 0.5°×0.5°.

A proper methodology aimed at surface wave tomography

open access: yesAnnals of Geophysics, 1997
When applying a methodology for obtaining the 3D shear-wave velocity structure of a medium from surface wave dispersion data, the problem must be considered with caution since one inverts path-averaged velocities and the use of any inversion method ...

Direct surface wave tomography for three dimensional structure based on surface wave traveltimes: Methodology review and applications

open access: yes地球与行星物理论评, 2023
Surface wave tomography using dispersion data to obtain isotropic and anisotropic shear wave velocity structures is a very efficient approach to study regional and global tectonics and deformation and to probe high-resolution crustal, upper mantle and ...

Review of progress in seismic attenuation tomography

open access: yes地球与行星物理论评, 2022
Global and regional seismic attenuation models reveal anelastic heterogeneous structures in the earth, which shed new light on the temperature, melt and volatile fraction of Earth's interior, as well as the geodynamic processes and source focal ...
