The models present a scenario of what might happen in a tsunami evacuation in Napier.
When the offshore fault that is one day expected to generate a massive tsunami off the coast of Napier ruptures, 77-year-old Valerie Norton won’t panic.
She’ll pick up the easy-grab supplies she has stored by the garage door of her beach-adjacent Westshore home, then she’ll mount her electric trike andhead for Onehunga Hill with as much confidence as she can muster.
She’s done it before. She knows the route and its little kinks and quirks.
Norton’s thinking is simple.
Experts estimate there’s a one-in-four chance of an 8.0 earthquake event on the Hikurangi Fault in the next 50 years.
That would, in all likelihood, send a devastating tsunami towards the North Island’s east coast, putting coastal Napier, and by consequence Westshore and by even more consequence, The Esplanade (where Norton lives), in an “inundation zone”.
That’s a fancy bureaucratic way of saying she’s in a place where the astonishing power of a tsunami could easily kill her if she stayed.
It’s the sort of reckoning that Norton knows will make her “absolutely charged-up” when and if the ground shakes angrily around her.
She doesn’t want that to cloud her decision-making before she turns her pedals.

Her key, she says, is planning.
“The thing that people don’t understand enough is that we’re going to be dealing with chaos,” Norton says.
“The nature of a major emergency like this is that it’s chaos – if you haven’t got chaos then you haven’t got a crisis.
“I don’t want to get sidetracked by the panic.”
New Zealand’s national Tsunami Hīkoi Week runs from March 9-15.
Today is also the 15th anniversary of the 2011 Japan earthquake and tsunami, which claimed more than 15,500 lives in the Tōhoku region.
The livestreamed images and video of it caused horror around the world and remain etched in the memory of many.
Norton’s done her hīkoi already and is sitting down with Hawke’s Bay Today to do this article to encourage others to follow her lead.
A former nurse, she bought her e-trike to help her keep her fitness and sanity as she recovered after a wave at the beach broke her leg eight years ago.
She’s not moving out any time soon, hence the need for a plan.
She’s far enough away from Ahuriri that she knows she doesn’t want to risk trying to get up Napier Hill, and putting her faith in a bridge across the harbour or estuary being usable and unblocked.
And if Norton can see a wave coming in that will arrive too soon to get to her spot, well, she’ll cross that path when it happens.
If there’s one thing she’s keen to promote with this article, it’s that the kind of conversations she’s had in her own head should be done out loud across the country, and ideally with entire families listening in.
Better to have a plan and then make a new one because the road ahead is cracked, than have no plan to begin with, is her feeling.
“It doesn’t have to be a big heavy kind of conversation, really,” Norton says.
“There are some real geographical challenges for residents in areas like Westshore in the event of a tsunami.
The offshore Hikurangi Fault is one of New Zealand's biggest known disaster threats.
“What Val shows is that the most important things are having a household emergency plan, knowing and practising your evacuation route, and recognising the natural warning signs: If it’s long or strong, get gone.
“Every step counts. Being prepared and acting quickly is how we will get through a tsunami event safely.”
Plan a route that takes you safely out of the zone.
Plan to walk or bike if you can. If everyone evacuates by car, roads can quickly become congested, delaying emergency services and those who need vehicles to get to safety.
Decide where you will go and make sure everyone in your household knows the plan in case you are not together.
Practise your tsunami hīkoi with your whānau, colleagues or classmates. If you have a pet, you could even walk them along your evacuation route.
