This CyberShake Precarious Balanced Rock Study will evaluate whether CyberShake ground motions are likely to knock over known Precarious Rocks. Here we define the processing inputs and outputs for this study.

Program inputs:

The user configurable parameters that should be input to our rotation program include:

  • CyberShake_Study_ID: 35 #CyberShake 1.0 = 35, CyberShake 2.2 = 40
  • CyberShake_Site_Name: PERR2 #Site Short Name
  • Rotation_Angle: -40.0 # Decimal Degrees from North
  • List of Ruptures (with wildcards permitted):
    • SourceID/*
    • SourceID/RuptureID/*
    • SourceID/RuptureID/VariationID

Program Outputs:

The program should produce an sqllite data file that can be queried to produce a report, with a list of rows for each rupture variation, with the following columns in each row

  • CyberShakeStudyID:
  • SiteName:
  • SiteNumber:
  • RotationAngle:
  • SourceID:
  • RuptureNumber:
  • VariationNumber:
  • NS_PGA (m/s/2):
  • NS_PGV (m/s):
  • NS_PSA5.0 (m/s/s):
  • NS_PSA3.0 (m/s/s):
  • NS_PSA1.0 (m/s/s):
  • NS_PSA0.5 (m/s/s):
  • NS_PSA0.1 (m/s/s):
  • Rot_PGA (m/s/2):
  • Rot_PGV (m/s):
  • Rot_PSA5.0 (m/s/s):
  • Rot_PSA3.0 (m/s/s):
  • Rot_PSA1.0 (m/s/s):
  • Rot_PSA0.5 (m/s/s):
  • Rot_PSA0.1 (m/s/s):

Steps

  1. ask sc what code to calculate peak amps
  2. define output format schema
  3. implement in db and table in sqllite
  4. write test
  5. Find location of Perris PBR
  6. Find nearest src/rupture
  7. Estimate Rotation Angle of each fault
