Abstract
New geophysical approaches for landslide investigation and monitoring were tested in the site of Gschliefgraben by the end of September 2009. Multiparameter airborne geophysics is a promising method for landslide investigation which could quickly determine the most susceptible areas to mass wasting (electromagnetics) and areas with active shallow mass movements (passive microwave); the content of radioactive elements could contribute to studying displacement or weathering degree. The introduced new techniques for mass movement monitoring and early warning (GEOMON4D and D.M.S. automated monitoring systems) proved, that such a combination of high-accuracy monitoring of displacement, ground-water level and ground temperature together with monitoring of the ground resistivity and self-potential temporal changes could definitely be an effective approach for early warning.
