This workshop was held at the Energy Hall Rooms A-D, James B. Hunt Library on the Centennial Campus of North Carolina State University.
Description
The forecasting of natural hazards, whether earthquakes, volcanic eruptions, floods, or landslides, poses a difficult challenge for earth scientists. Often a cascade of events accompanies a natural disaster — rain weakens the soil on a fire-scorched hillside, which gives way causing a large landslide, killing people and damaging property. Models of the principal disaster, the landslide, have many inputs, most of which are uncertain and many of which are affected by rain and fire. The trigger for the landslide is a problem of soil stability, which is then coupled with a mass flow model, in order to predict the regions at risk.
Scientists are beginning to understand the propagation of uncertainty through mathematical models, to enable predictions of the likely outputs given the uncertainty of inputs. More challenging is the propagation of uncertainty through coupled models. Outputs of the first model are usually not directly related to the inputs of the second model — so how does one effect the coupling? How do the assumptions and uncertainties of the first model propagate through to outputs of the second? Although coupling has been recognized as an important issue in quantifying uncertainty, the analysis of coupled models has only very recently been the subject of mathematical and statistical study.
Earth scientists, applied and computational mathematicians, and statisticians were invited to meet to examine modeling of coupled hazards, to identify the primary challenges in making predictions, and to devise effective strategies to advance methodologies for tackling these complex problems. There was an examination of the physics of the dominate geophysical process such as mudslides, landslides, avalanches, volcanic mass flow events and airborne ash clouds, and their attendant uncertainties. Researchers examined and applied new statistical methodologies to potentially show promise for the efficient coupling of hazards.

Title: Adapting to Climate Change: Lessons from Natural Hazards Planning
Description:This talk discusses lessons learned from natural hazard experiences that help communities plan for and adapt to climate change. Referencing from more than 260 case studies, Gavin Smith talks about how these lessons are used to examine diverse experiences, from severe storms to sea-level related hazards, droughts, heat waves, wildfires, floods, earthquakes and tsunami, in North America, Europe, Australasia, Asia, Africa and Small Island Developing States.
