The foreland is made of cretaceous limestones and it is represented by Salento, Murge and Gargano; the foredeep (Fossa Bradanica) is made of carbonate sediments settled during Plio-pleistocene, while Apennine thrust-belt is made of a series of terrigenous and marine deposits which settled in different basins that were stacked during the orogenic phase. At present these sediments are chaotic and present poor geotechnical characteristics.\nBoth climate and landslide data have been obtained from available databases that have been expanded by authors. Climate data covers a period from 1877 to 2008; time series from 60 rain gauges of which 47 are thermometric were selected. The climate database collects data about monthly temperature, rainfall and wet days, where a wet day is defined as a day in which precipitation is equal or more than 1 mm. A complex statistical treatment was done to correct the anomaly in the data before 1920, which consider as a wet day every day with any amount of precipitation. Climate indices related to temperature, rainfall, wet days and rainfall intensity (as the ratio rainfall/wet days) have been calculated for each month and for the hydrological year (from September to August of the year after), to obtain only a set of data for the whole region.\nLandslide data came from historical archives and newspapers and it covers a period from 1918 to 2006. In Apulia 237 landslide events were observed; landslide data were organised on the basis of municipal monthly time series. Monthly and annual indices concerning climate and landslide occurrence were defined and calculated.\nDuring the mean hydrological year the maximum number of landslides occur in January; between December and February there is the 61% of total. January 2003 was the month with the highest number of landslide events (61 events in the Subappennino dauno). \nThe trend analysis shows an increasing trend for landslides, despite the decreasing trend of rainfall and rainfall intensity and an increasing trend of temperature and wet days, climate favourable conditions to the reduction of landslide occurrence. These effects were justified highlighting the inappropriate land use in landslide prone areas.\nThe regional landslide distribution is not homogeneous: they are mainly concentrated on the Subappennino dauno, where the geological, morphological and geotechnical features are particularly favourable to landsliding. A more detailed analysis of climate and landslide occurrence data was conducted focusing on this regional zone."@en . @prefix ns12: . prodotto:ID261886 pubblicazioni:editore ns12:ID332 ; prodottidellaricerca:prodottoDi modulo:ID8212 , istituto:CDS066 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA9 , unitaDiPersonaleEsterno:ID18734 . ns12:ID332 pubblicazioni:editoreDi prodotto:ID261886 .
