Seismic hazard and alpine valley response analysis
Due to tourism and industrial development, urbanised areas located on deep-filled sediment alpine valley have undergone massive development. In the last decade, many seismological studies have shown that vibrations due to earthquakes are strongly amplified by alpine-specific soil conditions. Therefore, the fast building expansion in the alpine environment may have not been regulated by adequate levels of earthquake resistant design.
The project will build a transnational database which can be used in the whole alpine space for seismic hazard studies. Representative alpine valleys shapes and earthquake scenarios will be defined and the associated vibrations will be calculated. Generic alpine spectra and accelerograms will be proposed and compared with the level of protection currently pursued at a national or European (EC8) scale. The improved seismic risk knowledge will be disseminated to civil engineers and local authorities in order to reduce our vulnerability to earthquakes in the alpine space.
