Stress-induced seismic anisotropy is usually difficult to be separated or decoupled from
intrinsic or fracture-induced anisotropy in the subsurface. To distinguish the effects of …

Obtaining quantitative information on the state of stress in the crust can only be
accomplished by accessing the zone of interest by drilling. The borehole cavity, however …

The PP-wave reflection coefficient (ie, the ratio of the amplitude of reflected P wave to the
amplitude of incident P wave) has crucial practical applications in many field scenarios, such …

In a great variety of laboratory experiments over large intervals in stress, strain, and
frequency, rocks display pronounced nonlinear elastic behavior. Here we describe …

Anisotropy is ubiquitous in the Earth's crust, which causes the elastic characteristics of
seismic waves to change with direction. The study of seismic wave anisotropy is of great …

We develop a rock physics model based on nonlinear elasticity that describes the
dependence of the effective stiffness tensor as a function of a 3D stress field in intrinsically …

The assessment of viscoelastic properties of soft tissues is enjoying a growing interest in the
field of medical imaging as pathologies are often correlated with a local change of stiffness …

It is known that GPS time series contain a seasonal variation that is not due to tectonic
motions, and it has recently been shown that crustal seismic velocities may also vary …

Coda wave interferometry is a recent analysis method now widely used in seismology. It
uses the increased sensitivity of multiply scattered elastic waves with long travel-times for …

In this letter we describe the development of coda wave interferometry to determine
acoustoelastically derived third order nonlinear coefficients of a highly complex material …
