Building databases of multi-hazards and compound events

Multi-hazards and compound (climate-related or weather-related) events are characterized by complex dynamics with interactions between various physical processes across multiple spatial and temporal scales. Examples of these include the joint/successive occurrence of landslides and floods, or heatwaves, droughts, and wildfires.

In literature, databases of natural hazards are in general single hazard, like databases of floods (European Flood Database, AVI database), landslides (Global Fatal Landslide Database, AVI database), droughts (European Drought Observatory).

The assessment and understanding of multiple hazards and compound events require an integrated perspective, with the integration of data from multiple variables, combining multiple databases.

Here, we try to address this emerging need, illustrating a possibility of building a database of multi-hazards/compound events, and presenting some examples.
