In late 2011, a huge rock fall from the north face of the Pizzo Cengalo deposited more than 1 mio cubic meters of debris in the Bondasca Valley. Heavy precipitation events in summer 2012 lead to four large debris flows that reached the village Bondo, several kilometers downstream. In cooperation with the community Bregaglia, the canton Grisons and the EWZ electric power company, Geopraevent has installed a sophisticated early warning system that automatically leads to road closures and informs local authorities via SMS and pager messages. The webcam images, water level and precipitation measurement data are constantly available on our data portal. Read more here.
