Natural hazards pose an increasing threat to society. Processes change in magnitude and frequency; exposures are modified within short time periods, but over large areas and despite increasing knowledge; and damage tolls increase continuously. Therefore, a comprehensive disaster management is indispensable.
Within a sustainable management of disasters, the installation of early warning systems is an often required and in some instances a most suitable tool. This session is aimed to present different early warning systems, independent of whether these deal with landslides, floods, tsunamis, earthquakes (!?), droughts or meteorological events, to name a few only. Presentations are invited which address conceptual issues, already operating installations or planned systems. The session is explicitly not focussing on single hazards only (e.g. landslides) but rather addressing the different approaches taken to install, monitor, and analyse the hazards. In addition, any research on the establishment on warning thresholds, the communication chain and the prevention are welcome. We are looking forward to fruitful and interesting presentations and constructive discussions.
