The Concept
• Stepwise Realization: (1) Direct action(2) Longterm Support
• Modular ConceptCompatible with other systemsExpansion to other disasters (Volcanoes, land slides, meteorological hazards,....)
• Decentralized and open System (National/local Early-Warning-Centres)
• Transferable to other regions
• Recent technological developments
• Capacity Building
