Listen to the tsunami siren sounds
|If a tsunami warning is in effect, it will be posted on the National Emergency Management Agency website: civildefence.govt.nz and in the yellow box on the top right hand side of our website homepage.|
From time to time, visitors staying in coastal communities hear a siren sound (especially during hours of darkness) and become concerned that it’s alerting them to a tsunami warning.
Most commonly, the sound they’ve heard is the siren that summons members of the local volunteer fire brigade. These sirens generally have a rise/fall ‘air raid’ type tone.
More recently, new building alarms required to be installed have a siren tone which is very similar to Northland tsunami sirens and the difference can be difficult to detect. However, after four cycles of the sound, there is a voice message stating that it is a fire alarm.
The audio clips below are provided to help distinguish between the different siren types.
