vector-engine

Vector-valued PSHA calculations, based on the Openquake Engine Python library (https://github.com/gem/oq-engine)

Installation instructions

(For instructions on the EDF-specific Scibian environment, see link)

1. Set-up a dedicated vpsha virtual environment:
   $ python3 -m venv /path/to/virtual/env/vpsha

2. Activate the vpsha virtual environment:
   $ source /path/to/virtual/env/vpsha/bin/activate

3. Install the Openquake Engine Python library and dependencies:
   (vpsha) $ pip install openquake.engine

Run program

• Print help:
  $ python3 vectorengine/v-engine.py -h

• Full (N-D) hazard matrix calculation:
  $ python3 vectorengine/v-engine.py AreaSourceClassicalPSHA/test_job.ini full --imcm BakerCornell2006

• Find N-D (correlated) intensity-measure samples matching POE target value:
  $ python3 vectorengine/v-engine.py AreaSourceClassicalPSHA/test_job.ini optim -n 1
  (Note: POE target value must be specified in the configuration file)

• Compute full (N-D) hazard matrix and all N 1-D marginal hazard curve:
  $ python3 vectorengine/v-engine.py AreaSourceClassicalPSHA/test_job.ini calc-marginals

• Compute full hazard matrix and make N plots of the comparison between the associated 1-D marginal and the 1-D hazard curve:
  $ python3 vectorengine/v-engine.py AreaSourceClassicalPSHA/test_job.ini plot-marginals
