The Seismic Engineering Division carries out studies on the Design Earthquake needed for dynamic stability tests of foundations and earth works; Design Earthquake is provided by the soil maximum expected acceleration and by the Design Spectrum, which describes variation of the Seismic Coefficient (function of the resonance period of the structure) and local geological conditions.
The Seismic Engineering Division is also in charge of studying regional seismic risk ("macrozonazione sismica"), through which a representative design parameter distribution can be defined (soil maximum expected acceleration) and related to a prefixed recurrence period (100 or 500 years).
All "long-distance ground infrastructures" such as a highway or a railway track, need analysis so as to define updated and homogeneous project guidelines/parameters as far as all handwork is concerned. Such studies can therefore focus on more limited areas ("microzonazione sismica") and provide a more detailed analysis on the areas considered to be dangerous to the same extent. Areas developing easiliy or with more difficulty on a local level, for instance, which is important to consider when planning, colud then be identified.
