  • Bootstrap sampling to understand how many ruptures are needed for a given source
  • Source uncertainties (currently slip and hypo; but need to add uncertainty in G&P parametrization).
  • Velocity model uncertainties (random pertubations).
  • Explicit modelling of subduction zone sources in Cybershake
  • Neural Net for GMM trained with CS and validation results in order to use for distributed seismicity
  • New velocity model (i.e. with more basins)
  • Velocity model with tomographic refinement
  • Velocity model with site-specific 1D for HF method
  • Logic tree for hazard to consider different ground motion models (both empirical and simulated).  Weights for models are determined based on a neural net fit to the data in which all models start with uniform weight and the weights are then determined as a function of site location, magnitude, source to site distance etc.  Location component can be part of a convNet.
  • Ongoing improvements to the simulation code (topo, plasticity etc)
  • Paper which shows the theoretical benefits of forward simulation and domain optimization in terms of minimum total computation vs. recriprocity.
  • Consider other ERFs (i.e. not just Stirling et al 2012); UCERF3 method applied to NZ; RSQSim applied to NZ.
  • Extraction of deagg, and gm selection for a conditional IM hazard/im value.

Verification process:

Fault rupture (SRF) files:

...

Velocity model (VM) files:

...

  1. Check if given VM parameter (folder path) exists
  2. .p, .s, .d and params_vel.py files must exist
  3.  warns if model_params/coords/bounds etc don't exist using params_vel sufx in filename
  4.  params_vel matching hh/xlen vs nx for x, y, z
  5. file size = nx * ny * nz * 4 bytes, checked for .p, .s, .d
  6. if numpy available: checks first xz slice for >0 and not NaN in .p, .s, .d

Prioritization:

To do now:

  1. Automated IM plot on the map for all simulations 
  2. Automated standard post-processing for all simulations 
  3. Hazard curve calculations from simulated ground motions
  4. Empirical hazard calculations 

To do before v17.9:

  1. Config file for batch submission of the simulations 
  2. Verification code for param files for SRFs and VMs (e.g., transition frequency, grid size)
  3. Wall clock and number of cores estimations
  4. Automated check to see if the runs for LF, HF, and BB are done successfully 
  5. Comparison and combination of the simulated and empirical hazard analyses

To do, but no timeline for completion:
