Abstract

Continuous and episodic GPS observations between 1991 and 2004 show that Adria moves independently of both stable Eurasia and Nubia. Adria moves NNE at 3-4.5 mm/yr increasing from N to S relative to Eurasia and may be fragmenting along the Gargano-Dubrovnik seismic zone. The observed 2-3 mm/yr of N-S Adria-Eurasia convergence is taken up by contraction across a narrow (∼70 km) zone in the Eastern Alps and concomitant extrusion of the Alpine-North Pannonian unit. The Adria-Central Dinarides boundary is a broader collisional zone with intense 1-1.5 mm/yr shortening near shore and 2 mm/yr spread across the Dinarides. The remaining 1-2 mm/yr motion E of the Alps and NE of the Dinarides is absorbed by the inverted contracting Pannonian basin leaving no significant deformation above 0.5 mm/yr in the Western and Northern Carpathians, and European Platform.
