Tsunami evacuation maps

Online tsunami map

This tool shows the tsunami evacuation areas in our district. 

You can enter an address on the map. If it’s within the yellow highlighted area, you need to plan an evacuation route.

Be prepared with a plan if you ever need to evacuate due to a tsunami warning.

Note: Dec 2019 - GNS has been asked to peer review these maps, given the significance of changes proposed to our current evacuation areas. We will release this information as soon as we can... Read the full statement

Area evacuation maps

Locally generated tsunami

it’s extremely important that as a coastal community we do not wait for the release of revised maps or an official warning to be prepared for a tsunami.

A locally generated tsunami will be preceded by a very strong felt earthquake or a slow earthquake.

Use the natural signs as our warning, self-evacuation is the only option. 
If an earthquake is long or strong, get gone – long being more than one minute – strong being you can hardly stand – move quickly to higher ground or go inland.

The earthquake will be your only warning and you need to make the decision, if you're in the danger area, whether to go or stay. 

All of the maps have both local and distant evacuation zones on them.  You only need to get clear of the evacuation areas not miles inland or on top of the highest peak.  If you are on a part of the coast that isn't covered by one of the maps and you're evacuating you should get as far inland or as high as you can within a 20 -30 minute time frame (that's walking quickly not driving). 

If you can take a transistor radio you can listen for the all clear or otherwise you should wait 2 hours before returning home - if no tsunami has been generated. 

Distant tsunami - coastal communities evacuation maps

The maps define areas in coastal communities that are part of the planned evacuation areas for a distant and local tsunami. 
The only real credible threat from a distant tsunami to Gisborne communities is from Chile/Peru with around 11 - 15 hours warning.

Note: The community of Makorori will be totally evacuated so does not need a map.

The primary means of warning people to evacuate will be by door knocking in the areas identified in the maps.  Authorities will have between 10 - 12 hours to do this. Those at risk will be advised by Civil Defence volunteers, Police and NZ Fire Service.  There will also be information on all of our radio stations and on the civil defence website.

It is possible that evacuations for a distant event could last for 10 -12 hours, as there are many surges in a distant tsunami event.  If inundation does occur then some areas may be closed for sometime.
