CyberShake PBR Study

This CyberShake Precarious Balanced Rock Study will evaluate whether CyberShake ground motions are likely to knock over known Precarious Rocks

PBR Site

Low Freq seismograms

• PERRIS
• Lat/Long
• Nearby Faults:
  • Fault Name:
  • Src/Rupture Number:
  • Number of rupture variations:
  • Fault Parallel (degree's off North)

Broadband seismograms

• PERRIS
• Lat/Long
• Nearby Faults:
  • Fault Name:
  • Src/Rupture Number:
  • Number of rupture variations:
  • Fault Parallel (degree's off North)

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
