    The very particular situation represented by the town of Matera and its surrounding, as the "Parco archeologico storico-naturale delle Chiese rupestri del Materano" represents one of the most famous rupestrian settlement of the Mediterranean basin, mentioned in the UNESCO World Heritage. The need therefore to think of an efficient tool for research, for the territorial cataloging and for the planning of a proper development, in compliance with the requirements of the protection of cultural heritage, has continued to formulate more technical levels, such as analyzing risk factors, the drafting of the spatial constraints Map, the cooperation in the activities of territorial planning and actions for the protection and preservation, including the restoration and maintenance of monuments and sites. In the frame of a wider project focused on the mapping of the archaeological and cultural heritage of this area, we also planned the draft of the geo-archaeological risk Map of the rock churches located along the slopes of the Gravina stream, in front of the town. The research has experimented a model of analysis validated for the area, which could be extended in others territorial districts. The methodology employed for the evaluation of geo-archaeological risk represents an intermediate solution between a purely quantitative approach and the realization of qualitative considerations on dangerous phenomena (erosion, decay, collapse) and their potential consequences for cultural heritage. The draft of a Risk Map, offers information about the conservation and value of the archaeological heritage, and at the same time it is the necessary preliminary approach to the implementation of projects aimed at restoration and enhancement of the archaeological and monumental heritage

    In this paper are reported the geological and geomorphologic studies and the main results of the monitoring survey carried out on near the city of Matera in Basilicata region (southern It-aly). The “Sassi di Matera” are, since 1993, UNESCO World Heritage. In particular this work has been done in an area, the “Parco Archeologico Storico Naturale delle Chiese Rupestri del Materano", where fine rupestrian heritages are present. In this area, the considerable acclivity of the slopes and the lithological defects and intense fracturing state of carbonate rocks cause mass movements of the blocks in terms of rock falls, topples and rockslides. The potentially unstable carbonate blocks have been defined by geological and geomorphologic surveys with particular attention to the influence of the state of fractures of the blocks. Some specific sur-veys have been carry out and the data have been analyzed following the method of Mathe-son, (1983, 1989) to obtain information about the principal directions of fracture sets and to define an index of relative risk. Detailed analyses have been carried out in the test sites showed in figure 1 and the potentially unstable carbonate blocks that need survey have been defined. On the basis of these results a landslide monitoring activities it’s started and it’s still going on. The survey is made up by traditional survey system and new technologies: a tradi-tional topographic survey, GPS measures and a deformation measurement system. The adoption of a "mixed" approach, with the contemporary use of classical techniques and GPS and ground deformation measurement could allow the capability of combination/validation behind the data coming from each measurement system and could gives a more reliable in-formation about eventual mass movements of blocks
