"Scientific" Improvements
Functionality | To be included in this version | Might be included | Not this version | |
---|---|---|---|---|
Velocity Model | ||||
Basin Modeling | Add high priority basins | |||
VM | DEM extent increase + off-shore basin | |||
VM | VM Size decreased based on depth of rupture - sim duration changed to account for surface arrival times | |||
Tectonics | ||||
Subduction | Subduction Interface simulations - pending validation | |||
Simulation Method | ||||
SRFgen improvements for shallow crustal earthquakes from validation | Prelim validation needs to be done | |||
LF | ||||
200m simulation realisations | For all faults | |||
HF | ||||
Using Target dx/dy (stoch file more aligned with srf) | for single segment ruptures | |||
HF Scaling | HF DT decrease – using 0.01 for HF-DT, 0.005 for BB-DT | Scale stoch dx/dy down with area of fault. (when reach X number of subfaults double the dx/dy value) | ||
Sim methodology improvements | ||||
Stations | ||||
New Non-uniform Grid | Update in Christchurch / Wellington Region Finer Grid Real station update Only land stations in all versions of the grid (ref: Notes on lat,lon <-> x,y conversion) Similar number of stations | |||
Vs30 | ||||
vs30 improvements | Using geology only. Modified coastal areas with a distance to coast factor. | |||
Realisations | ||||
Additional Realisation Parameters (e.g. Magnitude) | Mw - Stress drop perturbation based on Leonard sigma and correlated together slip/rake/rise time perturbations come from the seed we pass to genslip Shypo / Dhypo unchanged from last version | |||
Change SRF slip seed generation | Randomised rather than same sequence | |||
Fault Sources | ||||
ERF | Create custom ERF for cybershake run | |||
Fault size rounding | Nearest 0.5k / 0.1k | |||
