| Zusammenfassung |
A database (Italian acronym CEDIT) of earthquake-induced ground failures in
Italy is presented, and the related content is analysed. The catalogue
collects data regarding landslides, liquefaction, ground cracks, surface
faulting and ground changes triggered by earthquakes of Mercalli epicentral
intensity 8 or greater that occurred in the last millennium in Italy. As of
January 2013, the CEDIT database has been available online for public use
(http://www.ceri.uniroma1.it/cn/gis.jsp ) and is presently hosted by the
website of the Research Centre for Geological Risks (CERI) of the Sapienza
University of Rome.
Summary statistics of the database content indicate that 14% of the
Italian municipalities have experienced at least one earthquake-induced
ground failure and that landslides are the most common ground effects
(approximately 45%), followed by ground cracks (32%) and
liquefaction (18%). The relationships between ground effects and
earthquake parameters such as seismic source energy (earthquake magnitude and
epicentral intensity), local conditions (site intensity) and source-to-site
distances are also analysed. The analysis indicates that liquefaction,
surface faulting and ground changes are much more dependent on the earthquake
source energy (i.e. magnitude) than landslides and ground cracks. In
contrast, the latter effects are triggered at lower site intensities and
greater epicentral distances than the other environmental effects. |
