Source Parameter Models A&SC&BC&Y Oversaturation with magNoYes (M1)no Aspect ratioYesYes (M2) Style-of-faultingYes yes DipNo / ?Yes? Hypo depth??yes HW/FWPlanned planned Static stress dropno Shallow slipNo no

Aleatory Variability A&SC&BC&Y Inter-event and intra- event terms Yes Mag dependence Yes Distance dependence ?Nono

Key Issues Oversaturation –Is it due to the aspect ratio, or the magnitude? Use of Aspect ratio –Are aspect ratios used in NGA consistent with aspect ratios currently used in hazard analyses? –Correlation with style-of-faulting Dependence on dip –Is this dip effects or a regional effect?

Key Changes from Previous Models Site classification –Vs30 –Depth of soil term (Z1.0 or Z1.5) Source –Oversaturation with magnitude –Aspect ratio as a key parameter Non-linear site response –Based on median rock PGA including event term
