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.
