article figure 1 the gps network stations already existing (red), stations realized with the project (yellow). arpa veneto, a partner in the project coordinated by the university of trieste s department of earth sciences, installed three gps stations: two of them along the well-known geophysical profile transalp, among areas characterized by high deformations (the feltre area and the montebellunamontello area), and a third in the lessini mountains. these gps stations provide the database for three processing centers: bayerische akademie der wissenschaften, university joseph fourier of grenoble, regione lombardia. the study and processing of the data will permit crustal deformation models of the alpine area to be confirmed or modified, with particular attention to seismogenetic areas for the prevention of seismic hazards. public site, to have geological stability, to have a power supply available, to have good gsm / gprs network coverage and last but not least, to have good accessibility. with these selection criteria, the following sites were identified in an early phase: monte avena in pedavena (bl), within the meteorological arpav station (acronym mave coordinates gbo 1718811, 5101525) city of montebelluna (tv), within a water supply reservoir (acronym mbel - coordinates gbo 1737062, 5074465) bosco chiesanuova (vr), within a primary school (acronym bosc coordinates gbo 1658670, 5051589) preliminary investigations and plan of the three sites selection criteria for the installation of three arpav stations the site choices were made in accordance with project objectives. the requirements were to place two of the stations in the southern alpine zone (between the valsugana fault and the southern alpine front if possible along the geophysical profile transalp), to locate a station in the verona area, to have an obstruction-free sky, to be located in a the identification of the three sites in the preliminary screening involved the analysis of each site s geological stability and rock substrate position. this screening was carried out for the monte avena (bl) and bosco chiesanuova (vr) stations by surface analysis and verification of plans of existing buildings in the areas. the screening for the station located in montebelluna (tv) involved a geognostic excavation that confirmed the presence of the montello conglomerate at 1.50 m from the surface. from figure 2 on the left a planning solution with a surface foundation in the presence of hard substrate in outcrop. figure 3 on the right a planning solution with a drilled deep foundation with micro-pillar in the lack of an outcropping substrate. latest news? visit www.geoinformatics.com 55 october/november 2009
