Conveners: Mark Stirling and Mike Oskin

SUMMARY: This workshop is being held in recognition of the growing body of work on the use of fragile geologic features (FGFs) to evaluate probabilistic seismic hazard (PSH) models, and the emergence of different methods of application and evaluation.

Key issues we would like to see addressed include the following:

1. What are the attributes of a useful FGF for PSH model assessment?
2. How should FGF fragilities and age estimates be developed?
3. What methods of FGF-PSH model evaluation are currently available or could be developed?
4. What range of expertise could meaningfully contribute to improving the FGF-PSH model evaluation methods in existence at present?
5. What do we need to do in order to develop formal guidelines for FGF-PSH evaluation?

We will bring together scientists possessing experience in studies of FGFs, and scientists not currently involved in FGF work but possessing relevant expertise. The following examples come to mind: geology and surficial processes that lead to the formation and identification of FGFs; alternative methods for fragility and age estimation; statistical methods of PSH model evaluation; and experience with the setting of guidelines criteria. We seek a clear definition of the state of the art of FGF-PSH model evaluation, and identification of the work and resources needed in order to achieve defensible evaluation methods for industry application.
