Tsunami

Information about tsunamis, evacuation zones and what to do during a tsunami.

Blue lines on Island Bay streets show tsunami-safe zones

Regular tsunami exercises are held in Wellington. You can prepare for a real tsunami by taking part, holding practice evacuations and checking your emergency plans and supplies.

News Release - Pacific Wave Tsunami Exercise - 07.11.11

Warnings for long-distance tsunamis come from the Ministry of Civil Defence and Emergency Management. They will be passed on using local radio, a loudhailer or warning siren.

If you feel a strong earthquake, or notice the sea is receding, or get a tsunami warning text message:

  • make for higher ground (at least 36m above sea level) - if you can't go higher, go further inland (at least 1.5km)
  • don't return for at least an hour or until told by the authorities
  • don't wait for a tsunami warning
  • avoid rivers and inlets, which magnify tsunami waves
  • turn on the radio, or come to this website or go to the WREMOnz Facebook page - follow all instructions and take essential items if you are told to evacuate
  • don't go to the beach to watch the waves
  • stay on the water if you're in a boat - don't return to port as the water levels and currents will be unpredictable.

Tsunami evacuation zones

The tsunami evacuation zones show the areas most likely to be hit by a tsunami - and therefore the areas you want to get out of quickly:

Safe zones and blue lines

Blue lines are being painted across some streets around the south coast and harbour. If you feel a large local earthquake (one that's so strong you can't stand up, or continues for a minute or longer), the blue lines show how far inland you need to go to stay clear of a tsunami wave.

The blue line project began in Island Bay.
