Seismic Reflection Tomography [PDF]
Exploration Geophysics, 1988 Velocity analysis in current conventional seismic processing is beginning to appear inadequate for dealing with the increasingly complex geological structures of interest today. Tomographic imaging using individual arrival traveltimes from a given reflector may offer the prospect of reconstructing in detail an accurate velocity field above that ...

Mantle dynamics and seismic tomography [PDF]
Proceedings of the National Academy of Sciences, 2000 Three-dimensional imaging of the Earth's interior, called seismic tomography, has achieved breakthrough advances in the last two decades, revealing fundamental geodynamical processes throughout the Earth's mantle and core. Convective circulation of the entire mantle is taking place, with subducted oceanic lithosphere sinking into the lower mantle,

Finite-frequency sensitivity of body waves to anisotropy based upon adjoint methods [PDF]
, 2007 We investigate the sensitivity of finite-frequency body-wave observables to mantle anisotropy based upon kernels calculated by combining adjoint methods and spectral-element modelling of seismic wave propagation.

Distributed acoustic sensing for seismic activity monitoring
APL Photonics, 2020 Continuous, real-time monitoring of surface seismic activity around the globe is of great interest for acquiring new insight into global tomography analyses and for recognition of seismic patterns leading to potentially hazardous situations.

S wave velocity structure below central Mexico using high-resolution surface wave tomography [PDF]
, 2010 Shear wave velocity of the crust below central Mexico is estimated using surface wave dispersion measurements from regional earthquakes recorded on a dense, 500 km long linear seismic network.

The case for dynamic subsidence of the U.S. east coast since the Eocene [PDF]
, 2008 The dynamic subsidence of the United States east coast is addressed using the discrepancy between regional and global estimates of sea level, elevation of paleoshorelines, and adjoint models of mantle convection that assimilate plate motions and seismic ...

Seismic fault identification method based on CBAM-TransUNet
Meitan xuebaoDetection and identification of faults are crucial in the process of coal exploration and mining, and the traditional manual method of fault interpretation can no longer meet the needs of actual production, and the deep learning-based seismic fault ...
