GNS science consultancy report 2013/131:
This report summarises the historical and geological record of tsunami in New Zealand. It updates a report on New Zealand’s tsunami hazards that was compiled in 2005. It incorporates new research and significant changes in scientific understanding, including lessons learned from the 2011 Tohoku tsunami in Japan. It focuses on the entire New Zealand coastline rather than just the main population centres. It also uses more advanced modelling to quantify the tsunami hazard. It concludes that over a 2500-year period, earthquake-generated tsunami are the major hazard, ahead of tsunami generated by seafloor landslides or volcanic activity.
