Dear User,
welcome to the first release of SISMA (Site Of Italian Strong-Motion Accelerograms) Web-Site. This is an archive of strong motion accelerograms recorded in Italy during the period 1972-2002. It includes 247 three-components uniformely processed recordings related to 89 earthquakes and 101 recording stations. The Web-Site allows to search data through three selection criteria (i.e. "Search Eqk", "Search Station" and "Search Recording") as listed in the menu bar on the headline. Selected Strong-Motion accelerograms and associated earthquake-, station- and ground motion-parameters can be displayed and downloaded.
The Database is the result of a joint project between the Sapienza Universita' di Roma and University of California, Los Angeles (UCLA) involving:
  - Giuseppe Scasserra - Ph.D. in Geotechnical Engineering at Sapienza Universita' di Roma, Italy
  - Prof. Giuseppe Lanzo - Dept. of Structural and Geotechnical Engineering, Sapienza Universita' di Roma, Italy
  - Prof. Jonathan P. Stewart - University of California at Los Angeles, USA
  - Prof. Fabrizio Mollaioli - Dept. of Structural and Geotechnical Engineering, Sapienza Universita' di Roma, Italy
Disclaimer:   The SISMA Web-Site is still under review. This first version is released to obtain comments and suggestion from users. Proper use of data is responsability of the user. Reference to the Web-Site can be reported as:
