In regard with the Attenuation Relationship for Seismic Hazard Analysis, with scenario below:
Site selection for seismic hazard: located on stable continent.
Source zones: At subduction zone approximately 500++km away from the site.
Question
Which attenuation relationship that is suitable to be used for seismic hazard analysis on stable continent with sources from subduction zone/shallow crustal zone?
I tried different Attenuation Relationship which derived for stable continent, subduction zone and shallow earthquake and get a different result but not exactly sure which relationship that represent the best with the above scenario.
