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

Prioritization:
To do now:
- Automated IM plot on the map for all simulations
- Automated standard post-processing for all simulations
- Hazard curve calculations from simulated ground motions
- Empirical hazard calculations
To do before v17.9:
- Config file for batch submission of the simulations
- Verification code for param files for SRFs and VMs (e.g., transition frequency, grid size)
- Wall clock and number of cores estimations
- Automated check to see if the runs for LF, HF, and BB are done successfully
- Comparison and combination of the simulated and empirical hazard analyses
To do, but no timeline for completion:
