	A framework that uses ~~graphs (~~networks~~) and a complex systems approach~~ to ~~identify the interactions between multiple hazards,~~ and ~~models~~ potential multi-hazard ~~impacts by considering a number of disaster~~ scenarios. A network of interconnected hazard ~~nodes (footprint, source)~~ and exposed nodes (e.g. houses, roads) is generated ~~and disaster scenarios modelled by cascading events~~ from ~~node to node, with relationships determined through~~ a ~~set~~ of ~~rules and conditions. Each scenario~~ is ~~a single hazard scenario, and impacts are combined in a database. However, it can be applied for multi-hazards,~~ by ~~modelling~~ the ~~cascading impacts from one node to another, based on frequency and magnitude thresholds~~.

	~~In theory, this framework can provide an understanding of complex interrelated hazards and cascading impacts that can be useful for disaster risk managers for preparedness and planning.~~
