This repo constains the sample scripts for reproducing simulations and the outputs of catalogues.

• scripts:

  • s01-domain.jl: create a fault domain
  • s02-greensfunc.jl: compute dislocation-stress Green's function
  • s03-parameters.jl: set fault parameters
  • s04-solve.jl: solve models
  • scanfunc.jl: functions for computing event catalogues from raw output data
  • solve.job: an example sbatch script for solving each model using one node (multi-threading within node, array job)

• outputs (for catalogue only):

  All model outputs are in HDF5. ic{#}/ denotes different initial conditions. extend/ contains extended simulations (up to 1200 or 1800 years, end-year is appened in those output names).

  Catalog output names are like resf-{parameter group}{value}.h5. LF denote left half fault, RF right half fault. Fields in the catalogue outputs are:

  • t: time step in second
  • ti: time step in second (downsampled if _stride != 1)
  • maxva: max velocity in m/s (LF)
  • maxvb: max velocity in m/s (RF)
  • maxvf: max velocity in m/s (whole fault)
  • mwa: moment magnitude (LF)
  • mwb: moment magnitude (RF)
  • ixba: event start time (LF), correspond to ti
  • ixbb: event start time (RF), correspond to ti
  • ixea: event end index (LF), correspond to ti
  • ixeb: event end index (RF), correspond to ti
  • riax: event initial rutpure along strike position (m) (LF)
  • ribx: event initial rutpure along strike position (m) (RF)
  • riaz: event initial rutpure down dip position (m) (LF)
  • ribz: event initial rutpure down dip strike position (m) (RF)

  Slip ratio output names are like srf-{parameter group}{value}.h5. Fields in the catalogue outputs are:

  • sr: seismic ratio
  • ar: afterslip ratio

  {output type}-s-{parameter group}{value}.h5 denote single VW model.

  ODEs solution output names are like otf-{parameter group}{value}.h5 (not included in this repo). They contains three fields:

  • t: time step (s)
  • v: velocity (m/s)
  • θ: state variable (s)
  • δ: displacement (m)
