Openquake 1.0 ground motion field calculator

Notes

The ground motion field calculator computes values of a scalar parameter - descriptive of ground motion intensity (e.g. Peak Ground Acceleration) - for a set of sites, given a single earthquake rupture. The calculator provides the options to compute:

• median ground motion

• uncorrelated ground motion

• spatially correlated ground motion using the Jayaram and Baker correlation model (Jayaram, N., J. W. Baker (2009). "Correlation model for spatially distributed ground-motion intensities", Earthquake Eng. Struct. Dyn, DOI: 10.1002/eqe.922)

• Assumptions

• Design

Still needed

• User stories:

  • Integrate the OpenSHA Scenario Shake Map calculator into the stripped version.
  • Implement event-set generation+ground motion field calculation workflow.
  • Add support for the generation of spatially correlated ground-motion fields.
  • Write a parser to read single event nrml.
  • Support generation of a set of ground motion fields from a single event.
  • Implement deterministic ground motion field calculation work flow.

• Suggested Implementation

• New features: *Add support for the generation of ground motion fields with spatial and inter-period correlation
