No-Subduction Datasets: Datasets Used to develop Directivity-Amplification Models
The datasets shown in these figures exclude sites where subduction contributes more than 30% of the total hazard.
VS30 = 760 m/sec for this dataset.
All-Source Disaggregation Datasets
The datasets shown in these figures include all the sites in California.
Note that disaggregation data was computed only for the NO-DIRECTIVITY PSHA.
