The collision between the European and the Adriatic plates in the eastern Alps is still a matter worth of interest concerning the Alpine evolution. Tectonic processes such as compression, escape and uplift are interconnected and shape this area. In order to understand past and ongoing processes better, the seismological field project named EASI (Eastern Alpine Seismological Investigation, a complementary project of the AlpArray project) has been completed. Fifty-five broad-band stations have been deployed through an associated international effort by the Geophysical Institute, Czech Academy of Sciences, Czech Republic; ETH Zurich, Switzerland; University of Vienna, Austria and INGV, Italy. The seismic stations registered continuously for one year along a 540 km transect from the Bohemian Massif, across the Eastern Alps to the Adriatic Sea (Trieste), and were dismantled in the summer 2015.The session aims to collect achievements from a broad range of previous geophysical and geological studies of the crust and the upper mantle in the Alpine region and to show the initial results from the just closed field experiment in order to stimulate fruitful discussions. We look for signs of the deformation within the Earth’s crust, structure of the upper mantle and dynamics of the region touching Trieste. We encourage contributions from previous and present studies carried out in the Eastern Alps. Presentations based on purely seismology, but also jointly with other geophysical and geological methods are welcome from both permanent observatory and temporary experiment data. Reinterpretations from earlier datasets with more modern/novel methods are also invited. We also aim to shed light on new clues and still pending questions regarding the Alps-Dinarides transition.
