Tectonic Inheritance During Plate Boundary Evolution in Southern California Constrained From Seismic Anisotropy

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The style of convective force transmission to plates and strain‐localization within and underneath plate boundaries remain debated. To address some of the related issues, we analyze a range of deformation indicators in southern California from the ...

Shear-wave polarization alignment on the eastern flank of Mt. Etna volcano (Sicily, Italy)

open access: yesAnnals of Geophysics, 1996
Recently, with the improvement of three-component seismic networks, studies revealing anisotropic characteristics in different regions have assumed great interest. In a complex volcanic area like Mt.

Varying Shear Wave Splitting Parameters Suggest Interaction Between Lithosphere and Asthenosphere in Arxan‐Chaihe Volcanic Field, NE China

open access: yesGeophysical Research Letters, 2022
Over 2 years of broadband seismic data from 27 temporary stations deployed in the Arxan‐Chaihe Volcanic Field (ACVF) provides us a valued opportunity to study mantle deformation and related geodynamic processes in NE China intraplate region. We estimated

Transient and steady-state shear banding in a lamellar phase as studied by Rheo-NMR [PDF]

open access: yes, 2012
Flow fields and shear-induced structures in the lamellar (L-alpha) phase of the system triethylene glycol mono n-decyl ether (C10E3)/water were investigated by NMR velocimetry, diffusometry, and H-2 NMR spectroscopy. The transformation from multilamellar

Density structure of Earth’s lowermost mantle from Stoneley mode splitting observations

open access: yesNature Communications, 2017
Large-low-shear-wave velocity provinces (LLSVPs) are present at the core–mantle boundary. Here, the authors show that splitting of Stoneley modes is probably due to a lower density of LLSVPs than the surrounding mantle because of the presence of post ...

Lightweight SFRC benefitting from a pre-soaking and internal curing process [PDF]

open access: yes, 2019
The presented research program is focused on the design of a structural lightweight fiber-reinforced concrete harnessing an internal curing process. Pre-soaked waste red ceramic fine aggregate and pre-soaked artificial clay expanded coarse aggregate were

The Influence of the North Anatolian Fault and a Fragmenting Slab Architecture on Upper Mantle Seismic Anisotropy in the Eastern Mediterranean

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The eastern Mediterranean hosts, within the span of a few hundred kilometers, extensional, strike‐slip, and collision tectonics above a set of fragmenting subducting slabs.

Reply to "Comment on 'Operational Earthquake Forecasting: Status of Knowledge and Guidelines for Implementation by Jordan et al. [2011]' by Stuart Crampin"

open access: yesAnnals of Geophysics, 2012
In his commentary on the International Commission on Earthquake Forecasting (ICEF) report [Jordan et al. 2011], Crampin [2012] claims that observable changes in shear-wave splitting can predict large earthquakes on short time scales with high reliability

Shear wave splitting as a proxy for stress forecast of the case of the 2006 Manyas-Kus Golu (Mb = 5.3) earthquake [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2012
The 2006 Mb = 5.3 Manyas-Kus Golu (Manyas) earthquake has been retrospectively "stress-forecasted" using variations in time-delays of seismic shear wave splitting to evaluate the time and magnitude at which stress-modified microcracking reaches fracture ...

Upper Mantle Anisotropy and Flow Beneath the Pacific Ocean Revealed by Differential PS‐SKS Splitting

open access: yesGeophysical Research Letters, 2023
Upper mantle anisotropy has been mapped beneath continents at high spatial resolution. Beneath the oceans, however, shear wave splitting constraints on upper mantle anisotropy are sparse, due to the paucity of seismic receivers. A technique that does not
