Seismic anisotropy beneath southern Iberia from SKS splitting

Short Note Seismic Anisotropy from SKS Splitting beneath Northeastern Tibet

The northeastern boundary of the Tibetan high plateau is marked by a 2 km topographic drop and a coincident rapid change in crustal thickness. Surface tectonics are dominated by the Kunlun strike-slip fault system and adjacent Kunlun concealed thrust. The main objective of the current study is to map lateral variations of seismic anisotropy parameters in this region along the linear INDEPTH IV ...

Complex anisotropy in D′′ beneath the eastern Pacific from SKS–SKKS splitting discrepancies

Seismic anisotropy and slab dynamics from SKS splitting recorded in Colombia

The Nazca, Caribbean, and South America plates meet in northwestern South America where the northern end of the Andean volcanic arc and Wadati-Benioff zone seismicity indicate ongoing subduction. However, the termination of Quaternary volcanism at ~5.5°N and eastward offset in seismicity underneath Colombia suggest the presence of complex slab geometry. To help link geometry to dynamics, we ana...

Significant seismic anisotropy beneath the southern Lhasa Terrane, Tibetan Plateau

[1] Shear wave splitting measurements using teleseismic PKS, SKKS, and SKS phases recorded by station LSA on the southern part of the Lhasa Terrane of the Tibetan Plateau reveal significant azimuthal anisotropy with a splitting time of up to 1.5 s, a conclusion that is contradictory to previous studies which suggested isotropy or weak anisotropy. In addition, systematic variations of the splitt...
