The data base in this SPP is generated in activity fields which entail operation of the AlpArray seismic station network covering the Alpine orogen both on land (activity A) and offshore-Liguria (activity B), as well as the deployment of two swaths of dense station networks crossing critically active areas of the Alps - the Apenninic and Southern Alpine orogenic fronts (activity C) and the transition between Eastern and Southern Alps (activity D). Geological investigation of well-exposed areas involves integrated structural, petrological, geochronological and/or surface studies (activity E) and is complimented by numerical modeling and tectonic reconstructions to analyse the dynamics of the lithosphere (activity F).
