Cascading hazards include earthquakes that leading to destructive landslides in addition to severe shaking, for example, or tropical cyclones that lead to storm surge and flooding in addition to wind damage.  These events represent a type of wicked problem that might be amenable to new types of analysis.  The focus of this session will be on understanding the dynamics of these complex earth systems.  Methods of interest might focus on scaling, nucleation, strongly correlated systems, noise-induced mode selection, fat-tailed statistics, new mathematical methods, computational approaches including cloud computing and high performance computation, numerical simulations, and web-based applications. Of particular interest are papers explaining and/or illustrating examples of coherent structures, self-adaptation, complex and chaotic dynamics, phase and mode locking in both low and high dimensional systems.
