Scientific meeting of experts to understand tsunami sources, hazards, risk and uncertainties associated with the Tonga-Kermadec Subduction Zone
Workshop
29 October - 02 November 2018
NZ Parliament Building ‘The Beehive’

Organiser(s) & Staff
Participation
By invitation only.
The Intergovernmental Oceanographic Commission (IOC) of UNESCO have agreed to support the ICG-PTWS WG1 – Understanding Tsunami Risk’, to better understand the uncertainties associated with two Pacific Subduction Zones; the Tonga-Kermadec Trench and the Ecuador-Colombia Border. This will be completed via two science experts meetings to be held over the next two years. The purpose of these expert meetings is to quantify earthquake and tsunami sources, hazards and risks to support holistic risk management (readiness, response, reduction, and recovery) and target suitable reduction projects. The first meeting will focus on the Tonga-Kermadec Subduction Zone. A very large tsunami associated with this Subduction Zone has the potential to cause widespread loss of life, and cause damage and disruption to multiple regions simultaneously. Many Southwest Pacific countries are exposed and vulnerable to destructive tsunami with significant consequences. This meeting will aim to focus on the uncertainties of tsunami hazard associated with this Subduction Zone and propose ways of managing the risk
