Documentation for the 2014 update of the United States national seismic hazard maps Documentation for the 2014 update of the United States national seismic hazard maps
The national seismic hazard maps for the conterminous United States have been updated to account for new methods, models, and data that have been obtained since the 2008 maps were released (Petersen and others, 2008). The input models are improved from those implemented in 2008 by using new ground motion models that have incorporated about twice as many earthquake strong ground shaking...

Geodesy- and geology-based slip-rate models for the Western United States (excluding California) national seismic hazard maps Geodesy- and geology-based slip-rate models for the Western United States (excluding California) national seismic hazard maps
The 2014 National Seismic Hazard Maps for the conterminous United States incorporate additional uncertainty in fault slip-rate parameter that controls the earthquake-activity rates than was applied in previous versions of the hazard maps. This additional uncertainty is accounted for by new geodesy- and geology-based slip-rate models for the Western United States. Models that were...

2014 update of the U.S. national seismic hazard maps 2014 update of the U.S. national seismic hazard maps
We held 8 regional and topical workshops across the U.S. to gather information for these maps. The maps were available to the public for comment during a 60-day period. A Steering Committee (9 experts) was assembled to review the inputs and results and provide additional insights. The maps have been presented at several professional meetings. In this talk we discuss: (1) CEUS, (2) WUS...

Rupture model of the 2011 Mineral, Virginia, earthquake from teleseismic and regional waveforms Rupture model of the 2011 Mineral, Virginia, earthquake from teleseismic and regional waveforms
We independently invert teleseismic P waveforms and regional crustal phases to examine the finite fault slip model for the 2011 Mw 5.8 Mineral, Virginia, earthquake. Theoretical and empirical Green's functions are used for the teleseismic and regional models, respectively. Both solutions show two distinct sources each about 2 km across and separated by 2.5 km. The source at the...

Uniform California earthquake rupture forecast, version 3 (UCERF3): the time-independent model Uniform California earthquake rupture forecast, version 3 (UCERF3): the time-independent model
In this report we present the time-independent component of the Uniform California Earthquake Rupture Forecast, Version 3 (UCERF3), which provides authoritative estimates of the magnitude, location, and time-averaged frequency of potentially damaging earthquakes in California. The primary achievements have been to relax fault segmentation assumptions and to include multifault ruptures...

Model and parametric uncertainty in source-based kinematic models of earthquake ground motion Model and parametric uncertainty in source-based kinematic models of earthquake ground motion
Four independent ground-motion simulation codes are used to model the strong ground motion for three earthquakes: 1994 Mw 6.7 Northridge, 1989 Mw 6.9 Loma Prieta, and 1999 Mw 7.5 Izmit. These 12 sets of synthetics are used to make estimates of the variability in ground-motion predictions. In addition, ground-motion predictions over a grid of sites are used to estimate parametric...
