View source for Chino Hills 1D and 3D

SCEC researchers are comparing the differences between Chino Hills simulations using 1D methods, based on the Broadband Platform, and 3D methods, based on SCEC 3D codes including Hercules-GPU and AWP-GPU.

== BBP Chino Hills Evaluation Methods ==

SCEC BBP researchers use the Chino Hills earthquake as a validation event. They have defined a 1D velocity model for the region, selected a consensus fault geometry and earthquake magnitude, and selected a set of ground motion observations for use in comparisons to synthetics.

== BBP Velocity Model for Chino Hills ==
In the following file, the first line indicates how many layers compose the velocity model. The following lines, one for each layer, describes the layer in details. The first column is the thickness of the layer (in kilometers). The second and third columns are Vp and Vs, respectively, both in km/s. The forth column contains the rho value (in g/cm3), while the last two columns contain the Qp and Qs parameters respectively.
