Geodetic Observations at the Eolian Islands (Southern Italy)

Abstract

In order to investigate the dynamic processes actually in progress in the Aeolian Islands a volcanic area in Southern Italy, high precision geodetic observations are employed. the knowledge of the kinematic field (vertical and horizontal displacements) and of the time-space gravity variations is an important constrain for any model describing the geodynamic processes involving the investigated area. Gravimetric (absolute, relative and gradiometric), photogrammetric, altimetric and GPS surveys are periodically carried out on networks spanning over the whole aeolian archipelagus. Recently a GPS network has been designed and surveyed to obtain a more complete knowledge of the kinematic field taking place in the area. This will improve the understanding of the tectonic processes acting in the area. The result of the interdisplinary approach are presented and discussed.
