The main objective of this Project is to make available through the Internet an updated and improved release of the Italian accelometer database (ITACA), originally developed within project S6, in the framework of the 2004-2006 DPC-INGV agreement.

To pursue this objective, the following activities are foreseen:

• addition of the most recent accelerometric records (2004-2007) from the National
  Accelerometer Network, operated by DPC;
• collection of records together with geological/geotechnical information on the recording
  stations from research institutions and public administrations other than DPC, once
  suitable agreements be signed between DPC and the institutions operating the
  network;
• completion of the set of monographs for the geological/geotechnical description of
  recording sites;
• increasing the number of stations with a quantitative description of the shear wave
  velocity profile, using low-cost methods for site investigations, mainly based on active
  or passive surface waves measurements;
• implementation of a web-GIS interface, allowing the interactive exploration of
  geographical data and of the related attributes.

Educational pages will also be prepared and added to the ITACA web portal, to introduce professionals to strong motion instrumentation principles, data processing, seismic site effects and strong-ground motion parameters.
In parallel to these activities, strictly related to the database improvement and implementation, further research activities are planned to enrich the database with innovative features, that are expected to make ITACA a reference search tool for professionals and researchers worldwide, namely:

• identification of accelerometer stations, where an “anomalous” seismic response is
  expected, either due to complex stratigraphic or topographic irregularities, or due to the
  interaction with man-made structures, such as dams.
• addition of new descriptive site parameters, to improve the reliability of site
  classification.
