Abstract

Natural hazard impacts are becoming increasingly complex, as demonstrated by real world examples of multi-hazards events. This requires major improvements of our current multi-hazard scientific modelling capabilities. High-quality earth observation (EO) data have the potential to contribute to improving our understanding of multi-hazard events and multi-risk impacts. However, to date there have been limited attempts to include EO data into the workflow of multi-hazard analysis, modelling, forecasting and added-value generation. In this contribution, we review recent developments in using EO data in multi-hazard and multi-risk assessment. We examine how EO data can support our practical understanding of multi-(hazard-)risk, and how this can be made accessible, useful and practical. We provide recommendations for improving EO information (tools, methodologies, accessibility, etc.) and an outlook on the potential evolution of using EO in disaster risk management.
