30 SEP: Residents of the coastal areas of New Zealand are being warned of a tsunami of more than 12 meters high.
The Wairarapa settlement of Lake Ferry is exposed to a high tsunami risk as latest data revealed that big wave in some centres has been underestimated and official evacuation zones will have to be widened.
All New Zealand coastal area are susceptible to tsunamis but areas that have had the maximum wave height have significantly increased include Northland; Great Barrier Island; the East Cape; Wairarapa; Auckland’s Manukau Harbour; the Coromandel (4-10m) and Bay of Plenty in the North Island. And Southland; Fiordland; Westland and Stewart Island all have greater risk in the South.
There are chances that in every 10 years New Zealand could be hit by a tsunami that would be about a meter high. But history shows that every 40 or 50 years there is what we would term a ‘dangerous tsunami’,” the director of Civil Defence emergency management John Hamilton said.
