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:
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.
- To organize a Western Basin and Range community
seismic-velocity modeling Working Group, contributing toward the goal of predicting
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).
- 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.
- We developed at each workshop detailed statements of research and data
priorities that can guide researchers contributing to the WBRCVM or helping to
- Louie wrote with help from participants a statement summarizing
our priorities for inclusion in NIW or Nevada research priorities statements
for FY10 NEHRP proposals.
