CyberShake Study 20.5

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

Values for database

We will calculate and store the following intensity measures in the database.

For deterministic seismograms:

• Store RotD50, RotD100 at the following 7 periods:

 10, 7.5, 5, 4, 3, 2, 1

For broadband seismograms:

• Store RotD50, RotD100 in the database at the following 21 periods:

 10, 7.5, 5, 4, 3, 2, 1, 0.75, 0.5, 0.4, 0.3, 0.2, 0.1, 0.075, 0.05, 0.04, 0.03, 0.02, 0.01, PGA, PGV

Durations

Values for database

We will store the following durations in the database for broadband seismograms:

• Acceleration significant duration at 5-75% and 5-95%, for both X and Y

Hazard Curves

We will calculate deterministic hazard curves at the following frequencies:

10, 5, 3, 2 sec

We will calculate broadband hazard curves at the following frequencies:

10, 5, 3, 2, 1, 0.5, 0.3, 0.2, 0.1 sec
