Reservoir stress path and induced seismic anisotropy: results from linking coupled fluid-flow/geomechanical simulation with seismic modelling [PDF]
Petroleum Science, 2016 We present a workflow linking coupled fluid-flow and geomechanical simulation with seismic modelling to predict seismic anisotropy induced by non-hydrostatic stress changes.

Evidence of reactivation of a hydrothermal system from seismic anisotropy changes [PDF]
Nature Communications, 2019 In this study, the authors monitor a hydrothermal fluid surge through seismic anisotropy changes at the Hakone volcanic field, Japan. The authors find the anisotropy changes to be set off by the seismic waves of the 2011 Tohoku-Oki earthquake, that ...

Depth-dependent anisotropy in the Earth’s inner core linked to chemical stratification [PDF]
Nature CommunicationsSeismic anisotropy in the Earth’s inner core (IC), including the heterogeneous, depth-dependent anisotropy structure, is a well-documented yet poorly understood feature plausibly related to the alignment of iron alloy crystals. Here, we report the effect

Major methods of seismic anisotropy
Earthquake Research AdvancesSeismic anisotropy reveals that seismic wave velocity, amplitude, and other physical properties show variations in different directions, which can be divided into lattice-preferred orientation (LPO) and shape-preferred orientation (SPO) according to its ...

Seismic Anisotropy in Subduction Zones: Evaluating the Role of Chloritoid
Frontiers in Earth Science, 2021 Subduction zones are often characterized by the presence of strong trench-parallel seismic anisotropy and large delay times. Hydrous minerals, owing to their large elastic anisotropy and strong lattice preferred orientations (LPOs), are often invoked to ...

Seismic Anisotropy—Introduction [PDF]
GEOPHYSICS, 2011 This special section is dedicated to seismic anisotropy, which is playing an increasingly more important role in our understanding and modelling of the subsurface. Most papers published in this section were presented at the 14th International Workshop on Seismic Anisotropy (IWSA), which was held on 12–16 April 2010 in Hillarys, Perth, Western Australia.

Seismic wave propagation in anisotropic ice – Part 1: Elasticity tensor and derived quantities from ice-core properties [PDF]
The Cryosphere, 2015 A preferred orientation of the anisotropic ice crystals influences the viscosity of the ice bulk and the dynamic behaviour of glaciers and ice sheets. Knowledge about the distribution of crystal anisotropy is mainly provided by crystal orientation fabric
