In April 2010 a lot of things are going on on earth: The eruption of the Eyjafjallajökull volcano underneath the like named glacier in Iceland keeps most of Europe busy and airplanes on the ground, while in Brasil and South Tyrol landslides took the lives of numerous people. The last mentioned event is somewhat connected to the work of terrestris: Since 2007 terrestris is involved in a project funded by the Federal Ministry of Education and Research (BMBF) dealing with “Integrative Landslide Early Warning Systems – ILEWS” led by researchers from the University of Bonn and the University of Vienna. The project is researching methods for landslide early warning systems with one study area located in the Swabian Alb and another site in South Tyrol. The project will end on April 30, 2010 but current events underline that these research activities are still hot topics.
