Workshop Program

November 2-4.5: Workshop at Te Papa Museum, Wellington, New Zealand
November 4.5-7: Field trip to South Island

Detailed Program below

Theme: This workshop will build on the outcomes from the NIED-TEM meeting at NIED in August, 2015. We would like to have the overall theme to be guided by PSHA. Specifically in the context of current PSHA methods and how each country is using new methods to improve hazard estimates. Topics not directly contributing to PSHA but that are aimed at improving overall hazard estimates are also welcome.

Outputs: We will aim for discussion papers based on the breakout sessions. We intend to produce a special issue for Seismological Research Letters based on the workshop and its outcomes.

Format:

  • Part 1: 5 Oral Sessions – including parallel sessions. We will aim for equal discussing time with presentation time.
  • Part 2: 2 Breakout sessions of 2 hours each
  • Part 3: Poster Sessions

Oral Session Themes:

1) Overview of the NSHM from each country including topics such as science, end-user needs, governing structure, and IT.
2) Data, Modelling & Uncertainty. How models are created, and, how uncertainty in the modelling: 1) is currently assessed, modelled and included; 2) could be better quantified; and 3) is or could be assessed in a rigorous testing framework. This includes application to all data and model aspects of SHA, e.g., paleoseismic data, geodetic data, seismicity models, GMPEs, ground-motion simulations, statistical testing to quantify improvements in models, etc. This session will probably need to be longer than the others
3) Time-dependence. Estimating time-dependent earthquake rates, at all time-scales, on faults, with cluster models and with alternative data-sets (e.g., slow slip, crustal strain, tremor).
4) Ground-motion prediction. Site-amplification, topographic amplification, long-period basin structure, geological structure, and scenario earthquake shaking.
5) Hazard and Risk Products. Risk modelling, online hazard products, etc

Breakout Sessions:

Field Trip: S. Island: Wairau Fault, Alpine Fault, Buller/Inangahua, Fox Glacier, Hanmer Springs, and Hope Fault.
