Rock fractures are crucial conduits for fluid flow in fractured rock masses. Three-dimensional
(3D) discrete fracture network (DFN) modeling approach, which can explicitly characterize …

Fluid‐filled fractures and microcracks are the most stress sensitive component of crustal rock
and often determine the pathways and volume of crustal fluid movement. If we are to …

Seismic measurements take many forms, and appear to have a universal role in the Earth
Sciences. They are the means for most easily and economically interpreting what lies …

Anisotropy is everywhere. Isotropy is rare. Round stones are collectors' items, and any
almost cubic blocks are photographed, as they are the exception. The reasons for rock …

Fracture networks play a more significant role in conducting fluid flow and solute transport in
fractured rock masses, comparing with that of the rock matrix. Accurate estimation of the …

The internal properties within and adjacent to fault zones are reviewed, principally on the
basis of laboratory, borehole, and seismic refraction and reflection data. The deformation of …

Tomographic inversion can be applied to seismic traveltime data to obtain a map of seismic
velocities in a rock volume, although the field geometries will not, in general, allow a …

I derive analytical expressions giving traveltime-offset curves for multilayered weakly
azimuthally isotropic and anisotropic media on terms of the elastic properties of each layer …

Three-component VSP borehole seismograms taken in the vicinity of an active normal fault
in California show strong systematic shear-wave splitting that increases with proximity to the …

Analytical studies have been carried out based on a modified displacement discontinuity
fracture model to characterize the relations between seismic properties and fractured rock …
