<strong>Alpine</strong> Integrated GPS Network: Real-Time Monitoring and Master Model<br />

for Continental Deformation and Earthquake Hazard<br />

The aim of the ALPS-GPSQUAKENET is to build up a high-performance transnational space geodetic<br />

network of Global Positioning System (GPS) receivers in the Alps.<br />

Aim<br />

The use of modern space based techniques gives us new potential<br />

to monitor and prevent natural risk, reduce economic<br />

losses, and save lives.<br />

The project is developed considering the lack of a transnational<br />

and high-performance space geodetic network of Global<br />

Positioning System (GPS) receivers in the <strong>Alpine</strong> <strong>Space</strong>. The<br />

project GPS array, within the millimeter-per-year precision,<br />

will represent the first ever installed transnational space geodetic<br />

network in the Alps. This will support the use of space<br />

based techniques that will provide the experimental basis of<br />

our scientific understanding of natural hazards in general and<br />

earthquakes in particular.<br />

Activities<br />

The project is successful due to its partnership that is represented<br />

by research institutions with powerful internationally<br />

recognised education and outreach programs, national and<br />

governmental agencies and regional public departments. The<br />

project strategy stands in the transnational structure of the<br />

partnership comprising both the geoscientists and end-users,<br />

providing an excellent means for the cross-training and interaction<br />

of regional employees and young scientists. The GPS<br />

array will satisfy the performance required by all the GPS applications<br />

and allow their implementations. The project covers<br />

different facets contributing to the reduction of natural hazards<br />

such as: crustal deformation for earthquake potential, meteorology,<br />

landslide monitoring, agriculture, navigation, transportation,<br />

mapping and surveying.<br />

Outcomes and results<br />

The results reached so far are:<br />

75% of the GAIN GPS array is operative<br />

Project data centre and web site fully working<br />

Earth model, for the whole Alps, of the first 350 km depth<br />

structure<br />

Model of lithospheric flow and stress pattern<br />

Earthquake moment tensors inversion for relevant earth-<br />

quakes in the Alps and surroundings<br />

Velocity field of: The French permanent GPS network in the<br />

Alps (REGAL), the Jura mountain and the junction between<br />

South-Eastern Alps and external Dinarides<br />

Monitoring of tropospheric humidity by GPS in south-eastern<br />

France<br />

Active fault monitoring: Rhone Alps, Friuli and western Slovenia<br />

Landslides monitoring using GPS: Piemonte and Trentino<br />

Foreseen:<br />

Full GAIN GPS array and processing of the data<br />

Possibly parts of the EUREF network have to be re-processed<br />

to gain first information before the end of the project<br />

Maps of the strain rate, displacements and distribution of the<br />

stress field at depth throughout the study area due to active<br />

tectonics and post-glacial rebound<br />

Visco-elastic + state and rate friction modelling of the stress<br />

evolution<br />
