An upgrade of the Italian catalogue (CEDIT) of ground failures triggered by earthquakes with epicentral intensity MMI-8 or greater occurred in the last millennium, is here presented. The ground effects include landslides, liquefaction, ground cracks, surface faulting and topographical changes. The first edition of the catalogue was released in 1997 and it included earthquakes up to 1980 A.D. The present release includes the following upgrades: the review of some relevant historical earthquakes (1805 Molise, 1905 Calabria, 1930 Southern Apennines, 1980 Irpinia); new data from recent earthquakes (1997 Umbria-Marche, 1998 Lauria, 2002 Molise and Palermo, 2009 L’Aquila); new parameters from the database of seismogenic sources (INGV-DISS3, 2010); references to the most recent lithological map of Italy by the National Environmental Institute (ISPRA); new location indexes from the National Institute of Statistics (ISTAT). Moreover, new statistical distribution of effects vs. geological and seismogenic features were derived as well as new relationships between earthquake magnitude and intensity vs. maximum expected distances for different ground failures.

Abstract
An upgrade of the Italian catalogue (CEDIT) of ground failures triggered by earthquakes with epicentral intensity MMI-8 or greater occurred in the last millennium, is here presented. The ground effects include landslides, liquefaction, ground cracks, surface faulting and topographical changes. The first edition of the catalogue was released in 1997 and it included earthquakes up to 1980 A.D. The present release includes the following upgrades: the review of some relevant historical earthquakes (1805 Molise, 1905 Calabria, 1930 Southern Apennines, 1980 Irpinia); new data from recent earthquakes (1997 Umbria-Marche, 1998 Lauria, 2002 Molise and Palermo, 2009 L’Aquila); new parameters from the database of seismogenic sources (INGV-DISS3, 2010); references to the most recent lithological map of Italy by the National Environmental Institute (ISPRA); new location indexes from the National Institute of Statistics (ISTAT). Moreover, new statistical distribution of effects vs. geological and seismogenic features were derived as well as new relationships between earthquake magnitude and intensity vs. maximum expected distances for different ground failures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
