GNGTS 2016 S essione 1.2 207 2013, 2012). The uncertainty associated with the velocity has been estimated by adopting the Allan Variance of the Rate method, introduced by Hackl et al. (2011) in order to take into account the correlated noise of the GPS daily position. The present horizontal kinematic field obtained at the end of time series analysis is shown in Fig. 2. It can be noted that the outer part of the Apennine belt (Adriatic margin) moves faster and with a greater eastward component, with respect to the inner belt (���������� �������� ��� ����� ������� �� ��� �������� ������ Tyrrhenian sector)� ��� ����� ������� �� ��� �������� ������ . The sites located on the Adriatic margin are characterized by velocities with values greater than 3 mm/year mainly oriented NE-ward. Conversely, the kinematic of the stations located on the Tyrrehenian sector are characterized by relatively low velocity, with values lower than 2 mm/year, and direction oriented from NW Fig. 2 – Horizontal kinematic pattern with respect to a fixed Eurasia, modelled using the Euler pole proposed by Altamimi et al . (2012): 54.23°N, 98.83°W, ω = 0.257°/Myr. The colours of circles indicate the velocity amplitudes following the chromatic scale on the figure.
