Tsunami and Hikurangi Subduction Zone Hazards Short Course 

New Zealand is vulnerable to tsunami from distant, regional, and local sources. Every tsunami threat brings new learnings, for both communities and organisations, about how we can better prepare and respond. With new research indicating a 1 in 4 chance of a Hikurangi Subduction Zone earthquake in the next 50 years, which could generate a large tsunami, it is vital that your organization is up to date with the latest science knowledge.

This two-day course, kindly sponsored by the Earthquake Commission (EQC), presents comprehensive, up-to-date Tsunami & Hikurangi Subduction Zone science and hazard knowledge from Aotearoa New Zealand's preeminent hazard researchers, from a range of disciplines. The presenters will also discuss valuable learnings from recent events, including the March 5th East Cape and Kermadec earthquakes and tsunami alert, and Hunga Tonga-Hunga Ha'apai eruption and associated tsunami.  

  • Part one - Covers the fundamental of tsunami science, tsunami hazard and risk modelling, tsunami risk mitigation and the processes behind tsunami warnings. 
  • Part two - Focuses on cascading hazards of the Hikurangi Subduction Zone. The Hikurangi subduction zone lies just off the coast of the East Coast of Te-Ika-a-Māui/North Island. This is Aotearoa New Zealand’s largest and most active fault, it poses enormous risk to our country, particularly our coastal communities. A large earthquake is likely to trigger a tsunami, widespread landslides, liquefaction, and permanent changes to our coastline.  

This course is designed for staff across Aotearoa New Zealand, in the planning and emergency management space. The content will be relevant to: Emergency management and response staff, planners, local and central government policy makers, hazard analysts, and any staff seeking this fundamental science knowledge to support their work.

The course begins 2nd of May 2022 will be held online, as a series of 2-hour workshops, with one workshop per week for six weeks. If Aotearoa shifts to the ORANGE traffic light setting before the start of the course, we will look to pivot to a 2-day in-person course in late May.

Any questions about the course content and suitability for you can be directed to Kate Clark or Georgia McCombe Georgia.McCombe@eastcoastlab.org.nz.  

For some introductory information on the Hikurangi Subduction Zone and its associated hazards please visit the East Coast LAB website for the What's On Our Plate module and Hikurangi Response Planning Toolbox

The course will be run as a series of webinars. Webinar links will be sent out in early April.
