Reliability and effectiveness of early warning systems for natural hazards: Concept and application to debris flow warning

Systems and Sensors for Debris-flow Monitoring and Warning

Debris flows are a type of mass movement that occurs in mountain torrents. They consist of a high concentration of solid material in water that flows as a wave with a steep front. Debris flows can be considered a phenomenon intermediate between landslides and water floods. They are amongst the most hazardous natural processes in mountainous regions and may occur under different climatic conditi...

An early warning on early warning systems!

Global early warning systems for natural hazards: systematic and people-centred.

To be effective, early warning systems for natural hazards need to have not only a sound scientific and technical basis, but also a strong focus on the people exposed to risk, and with a systems approach that incorporates all of the relevant factors in that risk, whether arising from the natural hazards or social vulnerabilities, and from short-term or long-term processes. Disasters are increas...

A Geospatial Service Approach towards the Development of a Debris Flow Early-warning Systems

Disaster prevention and management is a complicated task that often involves a tremendous volume of heterogeneous data from various resources. With its dynamic and distributed nature, service technology appears to be a good candidate for removing the communication barriers between various organizations and for facilitating the integration and sharing of distributed data. For it to succeed, howe...

WG Early Warning Systems

Early Warning Systems aim at detecting unclassified but potentially harmful system behavior based on preliminary indications and are complementary to Intrusion Detection Systems. Both kinds of systems try to detect, identify and react before possible damage occurs and contribute to an integrated and aggregated situation report (big picture). A particular emphasis of Early Warning Systems is to ...
