THE CRUSTAL VELOCITY FIELD MOSAIC OF THE ALPINE MEDITERRANEAN AREA: INSIGHT FROM NEW GEODETIC DATA

摘要

Geodetic techniques, such as Global Navigation Satellite System (GNSS), Synthetic Aperture Radar (SAR), satellite gravity missions, etc., have made significant contributions in monitoring temporal and spatial changes in Earth's lithosphere and atmosphere. A new crustal velocity field for the Alpine Mediterranean area (Farolfi & Del Ventisette, 2015) was determined by using a time series spanning 6.5 years of GNSS permanent stations. Thus, processing was performed by using state-of-the-art antenna phase center model, new recomputed satellite orbits and a new more accurate tropospheric model. The aim of this work is to calculate and analyze the spatial variations of continuous time series of GNSS permanent stations, to estimate crustal velocities in the Alpine Mediterranean area. The resulting velocity field gives a strong contribution in the framework of the contemporary geodynamics.
