Tsunami Sirens

Tsunami warning sirens

 

Aucklanders are advised not to be alarmed when the region’s tsunami sirens have their twice yearly test at noon on Sunday 30 September.


Coinciding with the start of daylight savings, the test sequence will be three sets of tones, each signaling a specific action that people would be advised take, in an emergency.

 

They will sound for one minute each and there will be 15 seconds between each set. In an emergency, tones will sound for longer.

 

In addition to testing the tsunami sirens Auckland Emergency Management will also be testing the Red Cross Hazards app, as well as sending messages to those signed up to emergency alerts.

Rodney

  • Omaha

Tsunami signals

The following signals will be used during an actual tsunami threat:

1. Alert signal (dash – dash – dot – dot) sounded for 15 minutes

This signal notifies residents that a tsunami threat has been received by Civil Defence.

Residents should respond by:

  • evacuating beaches
  • listening to the radio and TV for information
  • preparing to evacuate their homes and businesses if required.

2. Evacuate signal (dot-dot-dot) sounded in continuous burst for 15 minutes

The signal is used when a specific threat to the coastline has been confirmed.

Residents should respond by:

  • evacuating immediately to the nearest high ground
  • avoiding using personal transport (e.g. cars) unless absolutely essential, as this may cause congestion.

3. All clear signal (a continuous tone for five minutes)

The signal is used to notify that the threat of a tsunami has passed.

Residents should respond by:

  • returning to their home or business, if not affected
  • following the directions of the emergency services in affected areas.
