Seismic attenuation in Faroe Islands basalts [PDF]
We analysed vertical seismic profiling (VSP) data from two boreholes at Glyvursnes and Vestmanna on the island of Streymoy, Faroe Islands, to determine the magnitude and causes of seismic attenuation in sequences of basalt flows.

An Automatic Velocity Analysis Method for Seismic Data-Containing Multiples
Remote Sensing, 2022 Normal moveout (NMO)-based velocity analysis can provide macro velocity models for prestack data processing and seismic attribute inversion. Datasets with an increasing size require conventional velocity analysis to be transformed to a more automatic ...

Basin Research, Volume 37, Issue 6, November/December 2025.Synthesis of Late Burdigalian tectono‐stratigraphic events occurring in and around the southern Levant Basin. Highlighted are the active NW‐Se‐striking normal faults nucleating onshore Sinai and across the southern Levant Basin. The offshore strike‐slip fault networks are also highlighted and are believed to be related to the same event which nucleated

Tectonics, Volume 44, Issue 9, September 2025.Abstract The Hellenic forearc is one of the least understood forearc systems globally due to limited availability of high‐resolution imagery of its deep structure, especially landward of the Mediterranean Ridge. Here, we combine widely spaced high‐resolution multichannel seismic‐reflection profiles with seafloor morpho‐bathymetric analysis and ...

Post-stack inversion of seismic reflection data from the belvoir coalfield [PDF]
, 1995 Post-Stack inversion of reflection data in seismic exploration can be used to obtain detailed information about lithology variations in the zone of interest. Generalized Linear Inversion (GLI) has previously been applied as a useful tool to achieve this.

Three-dimensional joint inversion of traveltime and gravity data across the Chicxulub impact crater
, 2009 In 2005 an extensive new seismic refraction data set was acquired over the central part of the Chicxulub impact crater, allowing us to image its structure with much better resolution than before.

Image‐Domain Least‐Squares Migration Through Preconditioned Hessian
Geophysical Prospecting, Volume 73, Issue 7, September 2025.ABSTRACT Image‐domain least‐squares migration (IDLSM), which typically employs a diagonally dominant Hessian with narrow bandwidth for the inverse problem, provides an efficient deconvolution strategy for subsurface reflectivity imaging. Conventional methods often rely on the adjoint of the Born/Kirchhoff modelling operator to compute the Hessian ...
