OpenQuake 0.1 Risk Output

One of the goals of GEM is to produce Risk calculators and data sets with the intention to produce specific results, this blueprint aims to describe those results defined as Risk output. Different results can be obtained depending of which type of assessment is being performed.

Notes

• For one event-based calculations:

  • Loss/loss ratio maps
  • Standard deviation on the loss/loss ratio maps
  • Statistical data (exposed assets per intensity measure level, losses per intensity measure level, aggregate loss, uncertainty on the aggregated losses)

• For multi event-based calculations:

  • Loss/loss ratio curves
  • Loss/loss ratio maps (for given probabilities of exceedance or for the average value)
  • Aggregated loss for a given PE or average aggregated loss (if spatial correlation was considered)

• Assumptions

  • The date or sample data is available to produce the intended result.
  • The appropriate modules are in place to produce the previously mentioned results.
  • A nrml schema is designed to accommodate the intended result.

• Design Interfaces need to be created that will allow the risk engine to export the results once they have been computed.

• User stories:

  • Create a loss/loss ratio map.
  • Create loss/loss ratio curve.
  • Save risk curves to database as product.
  • Save risk maps to database as product.

• Suggested Implementation

The output component should be developed once all other schema, data and computational components have been put in place.
