Earthquake research

A magnitude 6.8 earthquake struck Gisborne at 8.55pm on 20 December 2007. Minor damage was widespread but in some locations, especially the CBD, a number of buildings were extensively damaged. 

Shaken Up cover pageWhilst the Gisborne earthquake was only a moderate event overall, it is the first earthquake in many years that affected a population centre as large as a provincial city. The response and recovery to this event, in particular addressing the areas of heavy damage, has provided the opportunity for learning to improve the management of future natural hazards. Several research organisations have conducted studies into the recovery experiences of the Gisborne community following the earthquake.

On 7 December 2009, 2 years on from the earthquake, some 140 government representatives, insurers, local authority staff, researchers, engineers and others from throughout New Zealand and Australia attended a half-day workshop called Shaken Up: Recovery Following the Gisborne Earthquake - at which the findings of this research were presented. The workshop was organised by researchers at Opus International Consultants’ Central Laboratories in Lower Hutt as part of a research programme entitled Social and Economic Recovery from Natural Disasters through Community Resilience (2004-2010), funded by the New Zealand Foundation for Research, Science and Technology (FRST).
