A study by TU Graz now identifies the triggers of such events. view more  Credit: © Kieffer - TU Graz/DCNA Mass movements such as landslides and hill-slope debris flows cause billions of euros in economic damage around the world every year. Between 20 and 80 million euros are spent annually from the disaster fund to repair disaster damage in Austria, 15 to 50 percent of which is attributable to mud flows and landslides. Now, a team of geologists from Graz University of Technology (TU Graz), in cooperation with the Burgenland state road administration, identified for the first time the chemical influencing factors and triggers for recurrent mass movements in fine-grained sediments. From results published in the journal Science of the Total Environment, preventive measures and strategies can be derived to guard against such events.
