    Spostamenti rilevati alle stazioni GPS della rete IGM95 poste nell'area dell'Appennino umbro-marchigiano dopo gli eventi sismici del settembre-ottobre 1997 (2008)

    Description: In this paper we present the GPS data collected at 18 stations of the IGM95 GPS network, in the colfiorito and Sellano areas. The data show ground deformations due to the largest earthquakes of the umbria-marche seismic sequence of September-October, 1997. The first two events, occurred on September 26, Mw=5.7 and Mw=6.0, produced planoaltimetric displacements up to 25 cm in the Colfiorito area. The October 14, 1997 earthquake, occurred near Sellano village and produced visible ground deformations that were not revealed at the GPS monuments dut to the unfavorable GPS IGM95 network configuration in this area. We present and discuss the whole geodetic data set collected in the area, useful to update the 3-D coordinates of the IGM95 GPS monuments, for scientific and civil applications.

    Data analysis of the first epoch GPS Algerian regional network (2008)
    Istituto Geografico Militare

    Publication Date: 2017-04-04
    Description: Within the aim to evaluate the present day crustal deformation of central western Mediterranean and northern Africa, a regional GPs network was planned and measured in the frame of the Tyrgeonet and Algeonet projects. We analyse GPS data collected at ten geodetic monuments located in Algeria, together with the Villafranca, Roquetes, Cagliari, Matera and Noto IGS permanent stations. This GPS network is deployed in a crucial area for the comprehension of the Western Mediterranean geodynamics, being located along the collision belt between the Eurasian and African plates. Moreover, some of the Algerian stations are located in the inner Algeria, along the Atlas deformed zone that released strong seismic events in the past, not yet studied by space based geodetic techniques. Other four stations are located in the tectonically stable of the Algerian erg. In this paper we describe the network and the data analysis of the first epoch surveys performed during june 1998.
