Impacts Phase

As part of the Impacts Phase, earthquake damage, recovery-time estimates for vital infrastructure and social ramifications will be evaluated for the region. Collectively, the results of these streams of investigation will allow the identification of specific interventions that, if applied, will have the greatest impact towards increasing the region’s resilience to earthquakes.

Work being undertaken as part of the Impacts Phase is focused on:

  • Engineering, using a comprehensive buildings and people model for the Wellington region to do comparative risk modelling to estimate the extent of damage, losses, and casualties.
  • Social Science, in particular a review of current planning and policy for earthquake hazard, and a welfare needs assessment to identify the spatial and temporal distribution of vulnerable populations post-earthquake and how to provide for their needs.

A brochure outlining the results of these earlier phases of work can be viewed here.

There are a number of publications (including journal articles, conference abstracts, progress reports and task completion reports) that document the research undertaken within the Impacts Phase of It’s Our Fault. Click here to access the publications listed below.
