CyberShake Study 20.5 is a CyberShake study in Southern California which uses Graves & Pitarka (2019) and includes stochastic high frequencies using the Graves & Pitarka high-frequency module from the SCEC Broadband Platform.
Output Data Products
Seismograms
- Deterministic (dt=0.05, nt=8000)
- Broadband (dt=0.01, nt=40000)
Intensity Measures
For deterministic seismograms:
- Store RotD50, RotD100 in the database at the following periods (7):
10, 7.5, 5, 4, 3, 2, 1
- Calculate RotD50, RotD100 and store on disk at the following periods (22):
10, 8.5, 7.5, 6.5, 6, 5.5, 5, 4.4, 4, 3.5, 3, 2.8, 2.6, 2.4, 2.2, 2, 1.8, 1.6, 1.5, 1.4, 1.2, 1
For broadband seismograms:
- Additionally, store RotD50, RotD100 in the database at the following periods (5):
0.5, 0.2, 0.1, 0.05, 0.02
- Additionally, calculate RotD50, RotD100 and store on disk at the following periods (13):
0.6666667, 0.5, 0.3333333, 0.25, 0.2, 0.1666667, 0.125, 0.1, 0.0666667, 0.05, 0.0333333, 0.025, 0.02
We will no longer calculate or store geometric mean.
Durations
- Store the following duration metrics in the database for broadband seismograms (calculate and store on disk for deterministic):
- Acceleration significant duration at 5-75% and 5-95% for both X and Y
- Velocity significant duration at 5-57% and 5-95% for both X and Y
- In addition to the above, calculate the following duration metrics and store on disk for both types of seismograms:
- Energy integral
- Velocity significant durations for 20-80% for velocity for both X and Y
- Acceleration significant durations for 20-80% for both X and Y
- Arias intensity
- Cumulative absolute velocity (CAV)
