Broadband Validation Events
Overview
The broadband platform provides three primary codebases for seismogram synthesis:
- URS
- UCSB
- UDSU
Three validation events are provided in the Broadband Platform:
- Northridge
- Landers
- Loma Prieta
Each of these events will be tested for each codebase. Although the platform allows codebases to be mixed and matched for low-frequency seismogram synthesis, high-frequency seismogram synthesis, and site response, validation events will be simulated with only a single codebase for now. Thus, there are nine unique simulation possibilities:
- Northridge with URS
- Northridge with UCSB
- Northridge with SDSU
- Landers with URS
- Landers with UCSB
- Landers with SDSU
- Loma Prieta with URS
- Loma Prieta with UCSB
- Loma Prieta with SDSU
These nine simulations will be run on both broadband.usc.edu and USC HPCC, and the results will be compared for accuracy.
Run Commands
The validation simulations were run using the standard run_bbp_2G.py start script. The following lists the run commands used with each codebase:
URS Simulations:
