摘要
Seismicity and GPS velocities in the southern peri-Tyrrhenian orogen record complex differential motion amongst crustal blocks constituting the tectonically fragmented paleotectonic domain, Adria. Coeval transpressional and transtensional belts within the orogen are kinematically coordinated and are consistent with displacement above a through-going basal decollement system that separates the heterogeneously deforming upper and middle crust from a presumed pattern of regular displacement within the underlying lithosphere. Seismicity and GPS velocities within the orogen reflect only indirectly the relative convergence between Africa and Eurasia.
