AdriaArray is a very important opportunity to improve the availability of measurements of seismic anisotropy in the region from the Adriatic Sea toward the east. Shear wave splitting data measured on teleseismic core phases are already available for most of the regions interested in the AdriaArray project. In particular, the Italian peninsula, the entire Alpine region up to the Pannonia basin, and the Carpathian belt and the Vrancea zone, but also toward its southeastern border, including Greece and the Aegean Sea, all these regions have a dense amount of shear wave splitting data already published. A database of this data will be made available and enriched using the results of the studies that are going on within the AdriaArray project. On the other hand, new types of analyses, such as for instance the splitting intensity of the anisotropy, have already been measured for the Alps and for the Italian peninsula as a whole, but are lacking toward the east, in the rest of the AdriaArray study region. In this work, the improvement in the application of splitting intensity measures on the AdriaArray data is described, starting from regions 1) where the possibility to compare the results with already available core phases seismic anisotropy measurements exists, and 2) where stations are enough dense to allow in the future the use of splitting intensity measurements to produce an anisotropy tomography as performed elsewhere (e.g. Italy).
