Communities around Otago’s coast have more certainty about which areas they should leave when a tsunami threatens, with the release of these online maps of evacuation zones.

The red zone includes the whole of the Otago shore and all beaches, including the Otago Harbour. This area is at risk from a tsunami of any size, including those designated a “beach and marine threat” rather than a “land threat”.
The orange zone includes land close to sea level including estuaries and the lower reaches of several rivers. These areas are at risk from tsunami with a wave height of between 1 and 3 metres above high tide level.
People in both the red and orange evacuation zones are advised to get out of the water, off beaches and move inland or uphill immediately they feel a long or strong earthquake, without waiting for an official warning.
The yellow zone is based on the area that would be affected by a wave height more than three metres above high tide level. A very large tsunami coming from a distant source – for example, South America – would prompt evacuations in the yellow zones.
Here are some questions people ask us most often about tsunami evacuation zones.
