CyberShake Review Process

We are defining a CyberShake Review Process that will define a series of verification checks that we perform on a CyberShake result before it is released to public for use.

CyberShake Data Products

Computational products that need review include:

• Hazard Map (at periods)
• Hazard Curve (multiple sites)
• SRFs
• Rupture Variations
• Seismograms
• Amplitudes
• Hazard Curves

Review Stages

We'll define a series of states that data products must pass through to be released.

• non started
• started->incomplete
• complete->preliminary
• complete->reviewed
• reviewed->released
• released->published

Confirming CyberShake Results

To migrate from complete->preliminary, a result must go through these checks to be

Completion check

• Individual DAQ’s confirmed as completed by DAGmanager
• No empty files

DB Consistency

• NAN check
• Consistency check confirms integrity of post-processing

Runtime logs:

• Runtime logs greped for error indocators, must return empty

Checks that are comprehensive:

• All seismogram files non empty
• All peak amplitude files non empty

• Check of Processing Stages
  • Input Checks
• GF Check
• SRF Check
• SRC Check
• Site List Check
  • Output Checks
• SRF
• Seismograms
• Amp files
• Amp db entries
• hazard curves
• Hazard maps

Reasonable Bounds Range Checks:

• Comprehensive PGA > 5g
• Min ground motion > 0.01 g

Comprehensive Check:

• Max PGV and min PGV plotted seismograms
• Alls Hazard curves inspection

Random Samples:

• 10 (of 400k) Seismograms inspected as “seismic”
• 1 forward simulation for a randon SRF
• SRF Visual inspections

Hazard Curve Evaluation

• Comparison of 3SA hazard curves for all sites GMPE to CyberShake

Map Evaluation Averaging-Based Factorization comparing new map to

• • National Seismic Hazard Map
  • Previous CyberShake Maps
