Set #1a: Broad-band ground motions (M = 7, R = 10 km, soil site)

See the report above for background regarding the selection of these ground motions.

	Spreadsheet documenting selected ground motions. Worksheets are provided to list a summary of the selected ground motions' metadata, their response spectra, and comparisons of the ground motion set's mean, standard deviation to comparable values predicted by ground motion models.
	Zip file containing acceleration time histories for the 40 selected ground motions. Fault-normal, fault-parallel and vertical components are included. (File size = 7 MB)

 

Set #1b: Broad-band ground motions (M = 6, R = 25 km, soil site)

See the report above for background regarding the selection of these ground motions.

	Spreadsheet documenting selected ground motions. Worksheets are provided to list a summary of the selected ground motions' metadata, their response spectra, and comparisons of the ground motion set's mean, standard deviation to comparable values predicted by ground motion models.
	Zip file containing acceleration time histories for the 40 selected ground motions. Fault-normal, fault-parallel and vertical components are included. (File size = 7 MB)

 

Set #2: Broad-band ground motions (M = 7, R = 10 km, rock site)

See the report above for background regarding the selection of these ground motions.

	Spreadsheet documenting selected ground motions. Worksheets are provided to list a summary of the selected ground motions' metadata, their response spectra, and comparisons of the ground motion set's mean, standard deviation to comparable values predicted by ground motion models.
	Zip file containing acceleration time histories for the 40 selected ground motions. Fault-normal, fault-parallel and vertical components are included. (File size = 5 MB)

 

Set #3: Pulse-like ground motions

See the report above for background regarding the selection of these ground motions. Further information on the technique used to identify these ground motions is available here.

	Spreadsheet documenting the properties of the selected pulse-like ground motions.
	Zip file containing acceleration and velocity time histories for the 40 selected pulse-like ground motions. Strike-normal, strike-parallel and vertical components are included. Separate sets of these time histories are provided for the original ground motions, extracted pulses, and residual ground motions. (File size = 16 MB)
	Link to web page listing selected pulse-like ground motions, and providing plots of pulse indicators and peak ground velocities for arbitrary horizontal orientations.

 

Set #4: Site-specific ground motions for Oakland

This set of ground motions consists of ground motions selected to match the uniform hazard spectrum and associated causal events for a site in Oakland, California. Forty ground motions are provided to represent the ground motion hazard at each of three hazard levels (2%, 10% and 50% probabilities of exceedance in 50 years).

	Spreadsheet documenting the properties of the ground motions selected for the 2% in 50 years hazard level.
	Zip file containing acceleration time histories of the ground motions selected for the 2% in 50 years hazard level
	Spreadsheet documenting the properties of the ground motions selected for the 10% in 50 years hazard level.
	Zip file containing acceleration time histories of the ground motions selected for the 10% in 50 years hazard level
	Spreadsheet documenting the properties of the ground motions selected for the 50% in 50 years hazard level.
	Zip file containing acceleration time histories of the ground motions selected for the 50% in 50 years hazard level
