Crustal and lithospheric scale structure of the Alps is known at a variable resolution and currently available seismological data show an inhomogeneous spatial coverage. There is an emerging consensus that national efforts need to be combined to obtain a clear, complete and integrated image of crustal and mantle structure all along the orogen. To foster associated projects on Alpine research, this session invites contributions that provide new results and point to open questions from the following perspectives: seismology (both passive and active source), earthquakes and microseismicity, geodynamics (including numerical models of evolution in both 2D and 3D), tectonic syntheses of the Alps and surrounding orogens, mega-blocks and micro-continents. Models and images indicating both vertical (subduction, gravitational instability, uplift) and horizontal (indentation, extrusion, rotation) displacements are of interest. Scales of investigations ranging from crustal to upper mantle depths are all welcome from the greater Alpine area, spanning over stable Europe, the Central Mediterranean (including the Ligurian and Adriatic Seas), the Carpathians, the Pannonian Basin and the Dinarides.
