CyberShake BBP Verification

This page documents our CyberShake Broadband Platform validation work, running the BBP validation events through CyberShake.

Events

We plan to run the following events from the BBP:

• Northridge
• Landers
• North Palm Springs
• Whitter
• Chino Hills

Process

• Identify about 10 stations from the BBP station list to run in CyberShake.
• Modify station list low-pass filter to 50 Hz.
• Use the Vs30 values from the BBP station list for both the low-frequency and high-frequency site response in CyberShake, for consistency.
• Run one realization using the SRF file which is generated by the BBP when run with one realization.
• Run the BBP validation events with the Graves & Pitarka modules to produce BBP results for comparison.
• Create an ERF in the CyberShake database containing all the validation events, with a unique source and rupture ID for each one.
• Save the SGTs in case we want to run additional realizations later.
• To interface with the BBP tools for generating data products, convert the CyberShake seismograms into BBP format seismograms

Data Products

We will produce the following data products to compare CyberShake results with BBP results:

• ts_process plot, comparing traces and response spectra.
• RotD50 comparison plots.
• Goodness-of-fit bias plots
• Map of GoF, by station
