  • Landslides caused significant damage to infrastructure.
    100,000 landslides affected an areas of 100,000 km2 due to high levels of weak sedimentary rocks and great shaking.

  • Most of the shaking occurred in areas with sparse population density.
    Kaikoura the most affected town with 5000 residents.
  • Expected $3.5 billion due to the economic damage to infrastructure and housing.
    Most significant issue was the destruction of transport which has had the largest long term impact.
    No access to Kaikoura which was a tourist town and highly reliant.
  • Rare seals lost habitat (pool (inlet) and waterfall as a result of land slipping) seals killed plus population disturbed in the rebuild.
  • Extremely effective response team.
