Previous Sprints

2019-10-03 - 2019-10-31 - BBP Sprint

1. Troubleshoot and finalize Vs30-based SVM site response module (verification)
   1. Done: Evaluate with all methods, user selects which site response module to use in simulation
   2. Done: Run all Part-A events and compare GP2014 and VS30 SeismoSoil results, share with modelers
2. Support UCSB improvements to their method
   1. Double corner, average rupture velocity rules
   2. Done: Re-run Part-A events
3. Continue validation event: L'Aquila
   1. Done: SRC/STL files, velocity model for all methods, with GFs and region parameters, all packaged for release
   2. Done: Run all methods, share results with groups, receive approval nod from each group
4. Update Part-A validation packages with latest version from CG with updated Vs30s
   1. Done: Run Part-A validation for all methods/events, share results with CG, do not expect big changes
5. Background: Update GP method to run multi-segment ruptures in a single pass
   1. Done: Run 3-segment Landers using new approach, compare results with previous runs
