Seismic anisotropy of the lithosphere and the upper mantle research group
Seismic anisotropy becomes one of the prime seismology topics of the future. The complex target – structure and development of the Alpine lithosphere and of the upper mantle - calls for being addressed with the use of variety of standard methods as well as with recently established or newly searched approaches. The AA Seismic Anisotropy Working Group will focus mainly on
- evaluation and modelling anisotropy of the lithosphere and the upper mantle for understanding structure and development of the broader area of the Alps. This includes studies of
- the large-scale fossil and/or deformation related anisotropy of the mantle lithosphere
- anisotropy due to flow in the sub-lithospheric mantle
- anisotropy of the crust and particularly improving methods and database for mapping and interpreting at a quality level and in scale as for mantle materials. This includes improved crustal anisotropy imaging by surface waves and body waves combined.
Among above topics, of particular interest are as follows:
- High-resolution models of mantle lithosphere fabrics from body waves in relation to ancient and recent processes that formed the Alps and their broader surroundings,
- Anisotropic tomography images of the heterogeneous upper mantle, origin and imaging mantle discontinuities (e.g., LAB, MLD),
- Constraints from texture in xenoliths and exposed mantle sections,
- The role of water in development of anisotropy, etc.
Particularly, applications of methods exploiting joint data sets (analyses/inversions) are of special interest.
The main task of the AlpArray Seismic Anisotropy group, whose research is based on the AlpArray data, is to coordinate activities among the members, either in collaborative or competitive way and to protect PhD students.
Jarka Plomerova ( ), Helena Munzarova ( ), with a help of Edi Kissling ( ), volunteer to lead communication and coordination among scientists and students interested to join the group.
Research Group Meetings
*** NEXT EVENT! ***
Meeting of the Seismic Anisotropy Research Group - Vienna 7 May 2020 (Thursday, 16:15-20:00)
The meeting will take place during EGU in a Splinter meeting on Thursday 7 May 2020 from 16:15 to 20:00.
SMI17 (Thursday 16:15- 20:00): AlpArray Seismic Anisotropy (AASA) Research Group: Anisotropic Structure of the crust and upper mantle in the Alps
Convener: Jaroslava Plomerova
Co-conveners: Götz Bokelmann , Ludek Vecsey
We invite scientists and students dealing with anisotropy of the crust and upper mantle in the broader Alpine region with the use of the AlpArray data and different techniques to particpate in the 3rd meeting of the AASA research group. The goal of the meeting is to upgrade mutual knowledge of current results achieved by different members of the AlpArray working group, particularly among the PhD students and young colleagues. We expect a short presentations about the progress of individual groups and results from shear-wave splitting evaluation by different methods tested upon selected earthquakes.
Write to the conveners for more information.

First meeting of the Seismic Anisotropy Research Group - Vienna 6-7 April 2019
The first meeting of the AlpArray Seismic Anisotropy (AASA) Research Group took place in Vienna on 6 - 7 April 2019, before the EGU 2019 Assembly.
WHERE:
University of Vienna (Dept. of Meteorology and Geophysics, Althanstraße 14, 1090 Vienna).
WHEN:
Saturday April 6 at 13:00 and to start presentations and discussion at 13:30. The meeting will most likely finish on Sunday around lunch time.
WHAT:
The workshop gathered activities on anisotropy of the crust and upper mantle in the broader Alpine region, in particular those using AlpArray data. The goal of the meeting is to create a forum for discussing work in progress, results, and plans of the different members of the AlpArray working group. We hope that particularly the PhD students and young colleagues will benefit from the meeting. There was short informal presentations in oral forms (~15min) or as posters, and there was time for discussion and further planning. Students (and postdocs) are encouraged to present themes of their theses, not only their current results.
