Multi-risk analysis and information system components for the Andes region (RIESGOS)

In recent decades, the risk to society due to natural hazards has increased globally. To counteract this trend, effective risk management is necessary, for which reliable information is essential. Most existing natural hazard and risk information systems address only single components of a complex risk assessment chain, such as, for instance, focusing on specific hazards or simple loss measures. Complex interactions, such as cascading effects, are typically not considered, as well as many of the underlying sources of uncertainty. This can lead to inadequate or even miss-leading risk management strategies, thus hindering efficient prevention and mitigation measures, and ultimately undermining the resilience of societies.

Therefore, experts from different disciplines work together in the joint project RIESGOS to develop methods for the evaluation of complex multi-risk situations, with the aim to transfer the results as web services into a demonstrator for a multi-risk information system. In this consortium, the ERA group is responsible for the reliability and risk assessment of lifeline systems under multi-hazard scenarios, with a special focus on the modeling of cascading effects.
