Subtopic “Drivers of Geohazards” explores the multi-scale coupling of the various solid earth system processes and their interactions with the surface and surrounding space.
Earthquakes, volcanic eruptions, tsunamis or landslides endanger billions of people worldwide. Only if we know more about the underlying physical processes can the effects be minimized. To this end, we are developing the next generation of Earth observation systems as well as innovative techniques for mode-ling and reliably interpreting the data. We are expanding our understanding of the drivers of the relevant geological processes. Our focus is on identifying, and understanding, the preparatory phase of hazardous events, including multi-hazard cascade processes.
To achieve this we focus on the following objectives:
- To understand why and where geohazards are occurring by the analysis of their drivers. We ex-ploit the unique set of multidisciplinary competences and research facilities provided by the invol-ved institutes to study the fundamental processes and interactions.
- To detect changes in the solid earth system over various temporal and spatial scales. We use ob-servables from land-sea-space monitoring frameworks and innovative data-mining strategies. The ultimate goal is to evaluate if and how the preparatory phases of catastrophic events can be detec-ted and integrated into warning systems and time-dependent hazard assessments.
- To characterize, understand, and model past, present, and future extreme and high impact events. We review the archives of previous events and develop new approaches to forecast events and cascade effects.
- To develop a shared vision of the unexpected to improve preparedness. We develop scenarios of future events, disseminate the potential associated losses, offer innovative training programs, and develop citizen science and crowdsourcing methods.
- To establish a globally unique onshore-offshore monitoring framework. We will integrate marine and terrestrial expertise of the members of the Topic partners.
- To establish a framework for the distribution of observations and model simulations to the global geoscience and stakeholder communities in a free and open manner.
