- Summary
- Since the 2010–2011 Canterbury Earthquake Sequence (CES), there has been heightened concern about liquefaction hazard throughout New Zealand. Much of the damage to residential buildings and infrastructure in Christchurch and the surrounding rural areas was caused by permanent ground damage, including liquefaction and lateral spreading in areas close to rivers, wetlands and estuaries (Brackley, 2012). The Natural Hazards Research Platform (’the Platform’) was established by the Government as a vehicle for determining a natural hazards research direction having regard to its critical strategic importance to New Zealand. The Platform, in consultation with Hawke’s Bay Regional Council (HBRC) (on behalf of the Local Authorities) and the Earthquake Commission (EQC), saw the merit in an assessment of the hazard and risk of the Hawke’s Bay Region to earthquake induced liquefaction, for the Local Authorities. The Platform provided funding for the project, along with co-funding from EQC and the Local Authorities (HBRC, Napier City Council (NCC), and Hastings District Council (HDC). Additional co-funding was provided by GNS Science from its Crown research funding.
