After that time many geophysical and geological studies were performed to evaluate the seismic characteristics of the 1908 eartquake, the seismic risk and the geological evolution of this region in the framework of Mediterranean geodynamics. In 1970, a geodetic network was set up across the Straits and was repeatedly measured with terrestrial techniques until 1980, showing a northward displacement of the Sicilian sites with respect to the Calabrian ones, between 1970 and 1971. In 1987, the old terrestrial network was surveyed again for the first time by the GPS technique, improving the accuracy of the coordinate determinations. Finally, in 1994, a wider network was established and surveyed again to collect additional GPS observations from a larger area across the Straits. In this paper, an analysis of the results obtained from the two GPS surveys with respect to those achieved by the terrestrial surveys (from 1970 to 1980) is given. This analysis shows there has not been significant crustal horizontal deformation across the Straits in the last 15 years. Although this crustal tectonic 'quiescence' corresponds to a low seismic activity level in the Straits area, terrestrial and GPS geodetic results would agree with Straits geophysical models excluding any aseismic deformations acting perpendicular to the Straits axis.184 25 - PublicationOpen AccessReports on Geodesy(1994-09-13)

This zone is a very interesting zone for geophysical and geodetic studies. In 1993 has been effectuated a GPS survey. This work shows the quality of the results and a comparison between GPS Geoid and the Italian Gravimetric Geoid performed by Politecnico di Milano.365 133 - PublicationOpen AccessGeodynamic implications of new geodetic measurements in the Messina Straits Area(2001)

The earthquake and the related tsunami caused thousands of victims and severe destruction in a wide area along the Sicilian and Calabrian coasts. After that time many geophysical and geological studies were developed to evaluate the seismic characteristics of the 1908 earthquake, the seismic risk and the geological evolution of the region in the framework of the Mediterranean geodynamics, characterized by the collision between the African and Eurasian plates. With the aim to evaluate the present crustal motion of this area, that undergone a recent tectonic evolution that produced an important uplift during the last 125 Kyears, since 1970 was started a geodetic research. A geodetic network was set up across the Straits and repeatedly measured with terrestrial techniques till 1980. In 1987, a 7 vertices network (4 vertices in common with the already existent network) was surveyed for the first time by the GPS space technique, improving the accuracy of the coordinate determinations. Finally, in 1994 a wider network was established and surveyed again to collect additional GPS observations about a larger area across the Straits. In this paper we provide a general geophysical description of the Area and the results obtained by the analysis of two GPS surveys (1987 and 1994) with respect to those achieved by the terrestrial surveys (from 1970 to 1980). Our analysis leads to exclude the occurrence of significant crustal horizontal deformations across the Straits in ha last 15 years; this conclusion is in agreement with current geophysical models that exclude any aseismic deformations acting in this area.214 103 - PublicationOpen AccessGPS measurements in the Central Mediterranean area(1992-09-23)
