1991年至2004年的连续和偶发GPS观测表明，阿德里亚独立于稳定的欧亚大陆和努比亚移动。亚德里亚以3 - 4.5毫米/年的速度向北北东方向移动，相对于欧亚大陆从北向南增加，并可能沿加尔加诺-杜布罗夫尼克地震带沿着破碎。观测到的2 - 3毫米/年的南北亚德里亚-欧亚大陆辐合被东阿尔卑斯山一个狭窄（类似于70公里）区域的收缩和阿尔卑斯山-北潘诺尼亚单元的伴随挤压所吸收。亚德里亚-中迪纳里德斯边界是一个更广泛的碰撞带，在海岸附近有1 - 1.5毫米/年的强烈缩短，在整个迪纳里德斯有2毫米/年的扩展。阿尔卑斯山和Dinarides东北方向的剩余1 - 2 mm/年运动E被反向收缩的潘诺尼亚盆地吸收，在西喀尔巴阡山脉和北方喀尔巴阡山脉以及欧洲地台没有超过0.5 mm/年的显著变形。
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 ( similar to 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.
