In the framework of the CARG Project, the University of Insubria is in charge of the realization of Sheet # 75 “Como”, 1:50 000. In 2008, the “Como” sheet turned into an International Project following the formalization of the collaboration between the Geological Survey of Italy/ISPRA, the Insubria University and the Swiss Geological Survey. This partnership is aimed at producing a joint geological map including data from both Italian and Swiss national territories, with obvious advantages for the scientific and applied aspects of the project. Here we focus on one of the recent results of our joint efforts, i.e. the analysis of the Quaternary evolution of the Monte Olimpino Backthrust (e.g., Bernoulli et al., 1989), and the evaluation of its potential neotectonic activity (sensu IAEA, 2002). The cross-border field mapping between Ticino and Lombardia resulted indeed in the finding of new exposures along the front of the Monte Olimpino Backthrust, that allow to recognize significant tectonic activity along this fault during the Quaternary (Sileo et al., 2007). In particular, we describe a new outcrop in the north-western sector of the urban area of Como at Borgo Vico, which has significant implications for the stratigraphy and the palaeoseismicity of the area.

Abstract
In the framework of the CARG Project, the University of Insubria is in charge of the realization of Sheet # 75 “Como”, 1:50 000. In 2008, the “Como” sheet turned into an International Project following the formalization of the collaboration between the Geological Survey of Italy/ISPRA, the Insubria University and the Swiss Geological Survey. This partnership is aimed at producing a joint geological map including data from both Italian and Swiss national territories, with obvious advantages for the scientific and applied aspects of the project. Here we focus on one of the recent results of our joint efforts, i.e. the analysis of the Quaternary evolution of the Monte Olimpino Backthrust (e.g., Bernoulli et al., 1989), and the evaluation of its potential neotectonic activity (sensu IAEA, 2002). The cross-border field mapping between Ticino and Lombardia resulted indeed in the finding of new exposures along the front of the Monte Olimpino Backthrust, that allow to recognize significant tectonic activity along this fault during the Quaternary (Sileo et al., 2007). In particular, we describe a new outcrop in the north-western sector of the urban area of Como at Borgo Vico, which has significant implications for the stratigraphy and the palaeoseismicity of the area.
