A review of the content, structure, accuracy, and com- pleteness of the Catalogue of Landslide OCcurrences in the Emilia-Romagna Region (CLOCkER) is presented. CLOCkER is a historical database, designed and developed for all types of landslides in the hilly-mountain area of the Emilia-Romagna section of the Northern Italian Apennines. Historical data have been gathered through a collection of numerous sources, includ- ing technical reports, historical archives, scientific literature, and newspapers. The information obtained, which has been evaluated to assess its temporal precision and spatial accuracy, has been recorded in a catalogue consisting of a Database Management System (DBMS) linked to a geographical information system (GIS) interface. The catalogue presently includes 14,416 records of documented landslide occurrences, dating from Middle Ages up to the present. The catalogue is associated with a landslide inventory, continuously updated by the Geological Survey of the Emilia-Romagna Region, where information on the shape, typol- ogy, and state of activity of more than 80,000 landslides is included. Our assessment of catalogue quality reveals a satisfac- tory spatial accuracy and a level of completeness comparable with the theoretical target proposed in the literature for complete inventories. Outputs indicate that CLOCkER can be a reference example useful for other regional historical landslide catalogues. Such reference datasets are useful for a wide range of landslide assessment purposes and can provide practical assistance for stakeholders involved in both scientific and technical fields, forming the basis for landslide temporal trend reconstruction that is essential for landslide hazard evaluation at different spatial-temporal scales. CLOCkER is open access, freely available online.

Abstract
A review of the content, structure, accuracy, and com- pleteness of the Catalogue of Landslide OCcurrences in the Emilia-Romagna Region (CLOCkER) is presented. CLOCkER is a historical database, designed and developed for all types of landslides in the hilly-mountain area of the Emilia-Romagna section of the Northern Italian Apennines. Historical data have been gathered through a collection of numerous sources, includ- ing technical reports, historical archives, scientific literature, and newspapers. The information obtained, which has been evaluated to assess its temporal precision and spatial accuracy, has been recorded in a catalogue consisting of a Database Management System (DBMS) linked to a geographical information system (GIS) interface. The catalogue presently includes 14,416 records of documented landslide occurrences, dating from Middle Ages up to the present. The catalogue is associated with a landslide inventory, continuously updated by the Geological Survey of the Emilia-Romagna Region, where information on the shape, typol- ogy, and state of activity of more than 80,000 landslides is included. Our assessment of catalogue quality reveals a satisfac- tory spatial accuracy and a level of completeness comparable with the theoretical target proposed in the literature for complete inventories. Outputs indicate that CLOCkER can be a reference example useful for other regional historical landslide catalogues. Such reference datasets are useful for a wide range of landslide assessment purposes and can provide practical assistance for stakeholders involved in both scientific and technical fields, forming the basis for landslide temporal trend reconstruction that is essential for landslide hazard evaluation at different spatial-temporal scales. CLOCkER is open access, freely available online.File | Dimensione | Formato | |
