|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| v17.8 | 15 (dominant in Canterbury) | 3 hypo and 2 slip dist per source | automated based on PGV>5cm/s; 15kmRup, 5km land cutoff Default depth and duration scaling | 0.4km regular grid, Vs_min=500 | Transition freq = 0.25Hz | ~3k Fitzroy | First implementation; Focus on running workflow and comparison with empirically-derived hazard curves | |||||||||||
| v17.9 + v18p4 (87 faults) | ~ (South Island) | hypo every 20 km along strike, 3 slip dist per source | Same as v17.8 | as for v17.8 | as for v17.8 | -- hours on Kupe | Focus on extending number of sources and srf uncertianties | |||||||||||
v18.5 | all North Island faults | Same as v17.9 | as for v17.9 | as for v17.9 | as for v17.9 | -- hours on Kupe |
| Running for the North Island sources to merge with 18p4 (and 17p9) to have a nation-wide hazard results | ||||||||||
v18p6
| 483 sources across NZ | Magnitude-dependant number of realizations one slip distribution per hypocentre | Pgv threshold of 2 cm/s | as for v17.9 | as for v17.9 | 150 k on Kupe |
| v17.11 (planning) | ~100 (Canterbury) | ?? Possibly more hypocentres down-dip | a. Improve depth scaling and duration scaling. Consider time step lengthening within stability limit | 0.2km regular grid, Vs_min=500 | Transition frequency = 0.5 Hz | ~500k Fitzroy(?) | Focus on producing NZ-wide output at lower freq transition | |||
