In Italy, intense or prolonged rainfall is the primary cause of landslides, and rainfall-induced slope failures occur every year, claiming lives, causing economic disruption, and producing environmental problems. In 2009, rainfall-induced landslides in Italy have caused more than 200 casualties (deaths, missing persons, injured people), in multiple...
Article
Determining when, or how frequently, landslides can occur in an area is of primary importance for erosion and landscape evolution studies, and for landslide hazard and risk assessments. Studies of the temporal occurrence of landslides over extended periods are rare due to paucity and reliability of information. In this work, we exploit a catalogue...
Article
A catalogue of historical landslides, 1951-2002, for three provinces in the Emilia-Romagna region of northern Italy is presented and its statistical properties studied. The catalogue consists of 2255 reported landslides and is based on historical archives and chronicles. We use two measures for the intensity of landsliding over time: (i) the number...
Article
This paper examines temporal correlations and temporal clustering of a proxy historical landslide time series, 2255 reported landslides 1951–2002, for an area in the Emilia-Romagna Region, Italy. Landslide intensity is measured by the number of reported landslides in a day (DL) and in an ‘event’ (Sevent) of consecutive days with landsliding. The no...
Article
Landslides are frequent and widespread geomorphological phenomena in Italy. A nationwide investigation completed by the Italian National Geological Survey has identified approximately 5×105 landslides, an average of 1.6 slope failures per square kilometre. Most of the mapped slope failures are known - or considered - to be triggered by intense or p...

Article
Full-text available
It is normally difficult to obtain quantitative information on triggered landslide events over time. Indeed, there are only a few records of series of triggered landslide events, of which none are extensive over time. As instrumental records of landslide events are virtually impossible to obtain for the last 50 years, we turn to a proxy for landsli...

The overarching aim of PROSLIDE is to exploit the potential of innovative input data, available ground truth data and novel modelling designs (i.e. data-driven and physically-based) at different scales to improve the predictability of where and when landslides will occur.
Project
The Apulia region is affected by multiple types of geo-hydrological instability processes such as sinkholes, flash floods and landslides. Considering such challenges the Regional Civil Protection and the Research Institute for the Geo-Hydrological Protection of the Italian National Research Council joined their efforts in a common project that aims at evaluating quantitatively the Apulia region susceptibility to geological hazard events. Furthermore the focus will be the definition of conceivable risk scenarios, needed for emergency planning and risk management. In particular, the project provides: i) critical revision of the data available from previous projects financed by the Apulia Region; ii) collection and organization of a database related to the occurrence of hydro-geological phenomena; iii) update of rainfall thresholds for shallow landslides; iv) implementation of a warning system for rainfall-induced landslide forecasting (SARF); v) setup of a landslide inventory map for the Daunia Apennine territory; vi) landslide risk analysis for ten urban centres in the Daunia area; vii) compilation of a database and a map of sinkholes and associated susceptibility analysis for the whole region; viii) definition of a methodological approach for the coastal instability analysis; ix) numerical modelling of geo-hydrological phenomena; x) development of a decision support system; xi) technical support to the Regional Civil Protection Department; xii) monitoring activity of representative instability processes.
