New release of the Italian catalogue of earthquake-induced ground failures (CEDIT)

Abstract

Italy is a country with a high seismicity, which is particularly concentrated along the Apennine Chain. In this area, earthquakes may exceed magnitude 6. The study of earthquakes and of their effects on the natural environment may provide a considerable contribution to national policies of defence against earthquakes and mitigation of their risk. This risk, however, is compounded by the fact that Italy has a high population density and a built heritage which is often inadequate to withstand seismic shaking.
The Italian Catalogue of Earthquake-Induced Ground Failures (CEDIT) is a database whose new release is available at www.ceri. uniroma1.it from January 2013. The new release arose from the requirement of reporting ground failures induced by earthquakes at national scale.
The first release of the catalogue (1997) was updated with the effects induced by earthquakes until 2009. The study of these effects involved:
- updating the bibliographic sources and references available for historical earthquakes already reported in the previous release of
CEDIT;
- adding data about earthquakes which occurred in Italy from 1984
to 2009.
