• runnable_code/ scripts to be run for parameter inversion or catalog simulation
  • ch_forecast.py estimates ETAS parameters and creates 100 simulations using the Swiss catalog
  • estimate_mc.py estimates constant completeness magnitude for a set of magnitudes
  • invert_etas.py calibrates ETAS parameters based on an input catalog (option for varying mc, and option to fix certain parameters available)
  • simulate_catalog.py simulates a synthetic catalog
  • simulate_catalog_continuation.py simulates a continuation of a catalog, after the parameters have been inverted. if you run this many times, you get a forecast. this only works if you run invert_etas.py beforehand.
  • visualize_fit.py makes plots which visualize the model fit to the data. this only works if you run invert_etas.py beforehand, and set store_pij = True.
  • predict_etas.py evaluates the model using the event-based log-likelihood on the test window
• config/ configuration files for running the scripts in runnable_code/
  • names should be self-explanatory.
• input_data/ input data to run example inversions and simulations
  • california_shape.npy shape of polygon around California
  • ch_catalog.csv Swiss catalog 1972 - 2021, used by ch_forecast.py
  • ch_rect.npy shape of rectangle around Switzerland
  • example_catalog.csv to be inverted by invert_etas.py
  • example_catalog_mc_var.csv to be inverted by invert_etas.py when varying mc mode is used
  • magnitudes.npy example magnitudes for mc estimation
