Learn how you can stay safe and informed during earthquakes and tsunamis in Palmerston North.  

Palmerston North sits on the active boundary between the Australian and Pacific tectonic plates, making our city prone to seismic activity. With a history of significant earthquakes and several active fault lines, it's important you understand the risks and be prepared for potential disasters.

Earthquake risk in Palmerston North

Palmerston North is at risk from several earthquake hazards, primarily from the Wellington Fault system and the Hikurangi subduction zone. A large earthquake in the city could cause:

  • Major damage to roads 
  • Major damage to essential infrastructure, such as water pipes, power, internet etc 
  • Surface ruptures in the ground 
  • Landslips
  • Liquefaction (when the ground behaves like a liquid).

The effects of a severe earthquake can be devastating. Ensure your family is prepared and know how to stay safe. The safety motto is simple: "Drop, cover, hold."

Tsunami awareness

Tsunamis are often triggered by large earthquakes that originate under the ocean. While Palmerston North is landlocked and not directly at risk, nearby coastal areas in the region are vulnerable. Should a large earthquake occur, especially near coastal zones, there is an increased possibility of a tsunami.

Long, or strong, get gone

If you're near the coast and feel a long or strong earthquake, immediately move to higher ground. The safety motto is simple: "Long, or strong, get gone."

We recommend if you’re a resident or visitor to coastal communities that you familiarise yourself with designated safe zones which are painted on the roads leading to each beach. Knowing where to go in the event of a tsunami could save your life. Check out the regional hazards page on the Horizons website to view the tsunami evacuation zones for your area. 

Though Palmerston North may not experience direct tsunami impacts, it could serve as a critical hub in the response and recovery process, particularly for those evacuated from affected coastal areas. Stay informed, stay safe, and be prepared.
