CyberShake Map Generation Procedure

CyberShake hazard maps are generated using an interpolated difference approach. This procedure is outlined below.
First, a high resolution GMPE basemap is calculated. This GMPE basemap uses a high resolution Vs30 map as well as the Z1.0 and Z2.5 from the velocity model used for the CyberShake study of interest (a new GMPE map is generated for each alternative velocity model). The ERF used in these maps is the same as used in CyberShake.
