Specify region for AbrahamsonGulerce2020SSlab model

[HORACIO ANDRES DOMINGUEZ]

Hi everyone,

I am trying to do a DSHA considering an inslab event located in South America. I want to use the Abrahamson & Gulerce 2020 model specifying the region as SAM in a gmpe logic tree. However I do not know where should I specify the region. I am unsing xml files for defining the gmpe logic tree and the seismic event. My gmpe logic tree is defined as:

<logicTree logicTreeID="lt1">
    <logicTreeBranchingLevel branchingLevelID="bl1">
      <logicTreeBranchSet uncertaintyType="gmpeModel" branchSetID="bs1" applyToTectonicRegionType="Subduction IntraSlab">
        <logicTreeBranch branchID="MontalvaEtAl2017SSlab">
          <uncertaintyModel>MontalvaEtAl2017SSlab</uncertaintyModel>
          <uncertaintyWeight>0.5</uncertaintyWeight>
        </logicTreeBranch>
        <logicTreeBranch branchID="AbrahamsonGulerce2020SSlab">
          <uncertaintyModel>AbrahamsonGulerce2020SSlab</uncertaintyModel>
          <uncertaintyWeight>0.5</uncertaintyWeight>
        </logicTreeBranch>
      </logicTreeBranchSet>
    </logicTreeBranchingLevel>
  </logicTree>

Thanks,

Horacio DF

You can try this:

<uncertaintyModel>
	[AbrahamsonGulerce2020SSlab]
	region = "GLO"
</uncertaintyModel>

Labels for the various regions are defined here: https://github.com/gem/oq-engine/blob/master/openquake/hazardlib/gsim/abrahamson_gulerce_2020.py#L32
