ust a range of amplitudes. Clarification ENSURE that uncertainties are included in the model that determine the range of seismic vibratory ground motion that can occur at a site as well as alternative magnitude and distance scaling behaviors in accordance with the level of analysis identified for HLR-SHA-A and the data and information in the update of the PSHA.

Clarification JUSTIFY ENSURE that the approach used to incorporate the site response analysis into the hazard analysis is justified (e.g., sources of soils and rock material properties used in the analysis, uncertainties in site characterization and material properties, data to identify the depth to bedrock, appropriateness of one- two- or three-dimensional analysis in relation to the site stratigraphy).
