January Workshop Schedule- with presentation links


The Nevada Seismological Lab convened in 2008 two brief workshops on creating a Western Basin and Range Community Velocity Model (WBRCVM), with generous support from the FY'08 USGS NEHRP-NIW panel. The workshops were both be held in Reno, in January and November.

The objectives of the workshops were two-fold:

  1. To organize a Western Basin and Range community seismic-velocity modeling Working Group, contributing toward the goal of predicting earthquake ground motions in urban areas and other sensitive sites. The community model will address seismic velocities at the crustal, basin, and geotechnical scales; and should contribute directly toward an overall Great Basin Community Velocity Model (to eventually include Utah, Arizona, and other area north and east).

  2. To hear advice from national experts who have constructed CVMs for other areas including Utah, to assess what CVM features most affect predicted ground motions, and thus prioritize our needs for geological and seismic-velocity data. WBRCVM construction efforts have been funded by the NEHRP-NIW program for FY09.
If you are interested in contributing to the WBRCVM, in using it to predict ground motions; or you have experience creating CVMs for such purposes in other regions, we hope you will be able to participate in the WBRCVM Working Group.
