CyberShake 18.3 is a computational study to perform CyberShake in a new region, the extended Bay Area. We plan to use a combination of 3D models (USGS Bay Area detailed and regional, CVM-S4.26.M01, CCA-06) with a minimum Vs of 500 m/s and a frequency of 1 Hz. We will use the GPU implementation of AWP-ODC-SGT, the Graves & Pitarka (2014) rupture variations with 200m spacing and uniform hypocenters, and the UCERF2 ERF. The SGT and post-processing calculations will both be run on both NCSA Blue Waters and OLCF Titan.
Contents
Status
This study is under development. We hope to begin in March 2018.
Science Goals
The science goals for this study are:
- Expand CyberShake to the Bay Area.
- Calculate CyberShake results with the USGS Bay Area velocity model as the primary model.
Technical Goals
- Perform the largest CyberShake study to date.
Sites
The Study 18.3 box is 180 x 390 km, with the long edge rotated 27 degrees counter-clockwise from vertical. The corners are defined to be:
South: (-121.51,35.52) West: (-123.48,38.66) North: (-121.62,39.39) East: (-119.71,36.22)
We are planning to run 817 sites, 786 of which are new, as part of this study.
These sites include:
- 145 new cities
- 10 new missions
- 46 new CISN stations
- 585 sites along a 10 km grid
- 31 sites which overlap with the Study 17.3 region for verification
A KML file with all these sites is available with names or without names.
