Session descriptions below. Thank you, John Anderson Ned Field Christine Goulet Peter Haeussler Morgan Moschetti Mark Petersen Peter Powers Sanaz Rezaeian Sessions website: http://www.seismosoc.org/meetings/2014/sessions.php Abstracts submission website: http://www.seismosoc.org/meetings/2014/absub/ Development of 2014 U.S. National Seismic Hazard Maps and Their Implementation in Engineering Applications The 2014 National Seismic Hazard Maps (NSHMs) produced by the United States Geological Survey (USGS) incorporate significant changes in the earthquake catalog, source models, and ground motion models. These seismic hazard maps are based on the USGS? assessment of the ?best available science? at the time of the update, and incorporate a broad range of scientific input models contributed by the seismological research community. The NSHMs are used to produce science-based products that will be considered for inclusion in future building codes, risk assessments, and other public policy applications. We invite papers that discuss major changes to the maps or to the input data and models (e.g., catalog, source models, ground motion models) since 2008; or discuss improvements in data, methods, and models that could be used in future maps. Papers that discuss the impact of the 2014 NSHMs on design maps and future building codes are encouraged. Alaska Update of the USGS National Seismic Hazard Maps The United States Geological Survey (USGS) plans to update the Alaska portion of the U.S. National Seismic Hazard Maps to produce science-based products that will be considered for inclusion in future building codes, risk assessments, and other public policy applications. These seismic hazard maps are based on our assessment of the ?best available science? at the time of the update, and incorporate a broad range of scientific input models and parameters. We invite papers discussing new geologic and geophysical information on Alaska seismic sources (faults and seismicity) and ground motion models. In particular we are interested in new paleoseismic fault studies, geodetic and geologic combined inversions of fault slip rates, and ground motion models for subduction and crustal sources. New Directions in PSHA: Ins, Outs, and Uncertainty In light of recent advances in earthquake science, data, and computational resources, probabilistic seismic hazard analyses (PSHAs) have increased in complexity. Such complexity manifests as larger logic trees, more sophisticated data-integration techniques, better understanding of input data uncertainties, and the computational capacity to undertake high-resolution simulations (e.g., CyberShake) and inversions for earthquake rate models (e.g. UCERF3). We invite papers on topics that include uncertainty analysis in PSHA, new approaches to gridded, area, and finite-fault source representations, logic-tree analysis and trimming, deaggregation, site-specific methodologies, computational algorithms, simulation based methods, urban hazard maps, new source and ground motion models, and other research or approaches related to PSHA. -------------- next part -------------- An HTML attachment was scrubbed...
