GPS monitoring and new data on slope movements in the Maratea Valley (Potenza, Basilicata)

The research brings out results obtained by three GPS monitoring campaigns undertaken between 1997 and 2000 on a grid of approximately 50 benchmarks. This process was supplemented by EDM monitoring carried out in a wider network of benchmarks than previously imposed. A comparison of different maps and other historical measurements complete the picture of long-term slope deformation. The presence of substained movements was confirmed over a century. The vector arrangement allow us to achieve a first model of ongoing gravitational processes: a spreading evolving lower-down in the valley into a large and deep flow.
