Get ready for Tsunami Hīkoi week

1 Tsunami Hikoi Week save the date tile

 

East Coast LAB and Hawke’s Bay Civil Defence Emergency Management Group (HBCDEM) are encouraging whānau, schools and businesses in the region to practise their tsunami evacuation routes as part of Tsunami Hīkoi week, which runs from 7 to 13 March.

Tsunami Hīkoi week is an annual initiative held by East Coast LAB, to mark the anniversary of the 2011 Japan earthquake and tsunami, which claimed the lives of 15,500 people in the Tōhoku region. The aim of Tsunami Hīkoi Week is to encourage people to learn and practice their tsunami evacuation route.

East Coast LAB project leader Georgia McCombe says it is important to know what to do if you feel a long or strong earthquake and whether you are in a tsunami evacuation zone.

“The East Coast of the North Island is especially at risk of tsunami, due to our proximity to Aotearoa’s largest and most active fault – the Hikurangi Subduction Zone. Because of this everyone who lives, works, or plays in a tsunami evacuation zone should know how to prepare for tsunami and know what to do to be safe,” Georgia McCombe said.

“Tsunami Hīkoi week is great chance for people to familiarise themselves with their evacuation route through a tsunami hīkoi. A tsunami hīkoi is a walk that takes you along your tsunami evacuation route either inland or towards high ground,” Georgia McCombe said.

“Walking the route you would take in an actual event is one of the best ways to prepare for a tsunami, as well as learning the natural warning signs of a tsunami: If an earthquake is long or strong, get gone,” Georgia McCombe said.

HBCDEM Group Manager Ian Macdonald says this year’s Tsunami Hīkoi week marks the 11th anniversary of the 2011 Japan earthquake and tsunami, with vital lessons learnt from that event.

“We know that practicing your tsunami hīkoi works because it helped save the lives of 95 per cent of people in Japan in 2011,” Ian Macdonald said.

“Practicing your evacuation walk will allow you to respond quicker when the real thing happens. It means that you, your workplace, household and whānau can all act immediately.

“Regularly practicing the walk, run or bike ride to your tsunami safe location is a great way to stay prepared and ensure you and your whānau will waste no time in reaching it,” Ian Macdonald said.

Ian Macdonald said that while all people around the country are managing a lot right now with COVID-19, it’s important not to lose sight of the other emergencies that can happen in Aotearoa.

“A local source tsunami could occur any time and could arrive in minutes, with no time for an official warning. So, it’s important to recognise the natural warning signs and act quickly. Remember, if you feel a long or strong earthquake, get gone. Self-evacuate immediately to high ground or inland,” Ian Macdonald said.


How to practise your tsunami hīkoi

  • Check to see if your home, work, school or community meeting place is in a tsunami evacuation zone on the Hawke's Bay Civil Defence Emergency Management group website.
  • Get to know the natural warning signs: If an earthquake is long or strong, get gone. Self-evacuate immediately to high ground or inland.
  • Plan a route that takes you safely out of the zone.
  • Plan to walk or bike if you can. If people try to evacuate in their vehicles, the roads will quickly become congested, especially if they are already severely damaged by the earthquake.
  • Decide where you will go (and make sure everyone in your family knows, in case you’re not all together). Your safe location will ideally be with friends or family, so make sure they know your plans.
  • Practise your tsunami hīkoi with your family, colleagues or classmates. If you have a pet you could walk them along your tsunami evacuation route.

Notes to editors

  • The Hikurangi Subduction Zone is where the Pacific plate subducts, or dives down, westward under the Australian plate. Subduction zones generate the largest earthquakes and tsunami in the world, and just like in Japan, the Hikurangi Subduction Zone is close to shore and a tsunami from this source would arrive within minutes of a long or strong earthquake, allowing no time for official warnings.
  • Recent research, led by Charlotte Pizer from Victoria University of Wellington, indicates a 1 in 4 chance of a Hikurangi Subduction Zone event in the next 50 years.
