Comprehensive Guide to Natural Hazard Preparedness in Dunedin, New Zealand

Dunedin, located in the Otago region of New Zealandโ€™s South Island, is a beautiful city known for its rich history, stunning landscapes, and vibrant culture. However, like many parts of New Zealand, it is also prone to certain natural hazards due to its geographic location and geological features. Being prepared for these hazards is essential for both residents and visitors. Below is a detailed guide to help you understand the risks, prepare effectively, and respond appropriately.

1. Types of Natural Hazards in Dunedin

Dunedin is susceptible to several natural hazards, including:

a. Earthquakes

  • Risk Level: Moderate. Dunedin is not as seismically active as other parts of New Zealand (e.g., Wellington or Christchurch), but it is still at risk due to its proximity to fault lines.
  • Cause: New Zealand lies on the Pacific and Australian tectonic plates, making the entire country prone to earthquakes.

b. Flooding

  • Risk Level: High in certain areas. Dunedin has experienced significant flooding in the past, particularly in low-lying areas like South Dunedin.
  • Cause: Heavy rainfall, poor drainage, and rising sea levels.

c. Landslides

  • Risk Level: Moderate to High. Dunedinโ€™s hilly terrain makes it prone to landslides, especially after heavy rain or earthquakes.
  • Cause: Saturated soil, steep slopes, and seismic activity.

d. Tsunamis

  • Risk Level: Low to Moderate. Dunedinโ€™s coastal location means it is at risk of tsunamis, though the likelihood is lower compared to other parts of New Zealand.
  • Cause: Underwater earthquakes or volcanic activity in the Pacific Ocean.

e. Severe Weather (Storms and High Winds)

  • Risk Level: Moderate. Dunedin can experience strong winds, heavy rain, and occasional snow in winter.
  • Cause: Its location in the path of southern weather systems.

2. Practical Safety Measures

a. Earthquake Preparedness

  1. Before an Earthquake:

    • Secure heavy furniture and appliances to walls.
    • Identify safe spots in your home or accommodation (e.g., under sturdy tables or against interior walls).
    • Prepare an emergency kit (see details below).
    • Download the GeoNet app for real-time earthquake alerts.

  2. During an Earthquake:

    • Drop, Cover, and Hold: Drop to the ground, take cover under sturdy furniture, and hold on until the shaking stops.
    • Stay indoors if you are inside; avoid doorways and windows.
    • If outdoors, move to an open area away from buildings, trees, and power lines.

  3. After an Earthquake:

    • Check for injuries and hazards (e.g., gas leaks, damaged structures).
    • Follow local authoritiesโ€™ instructions via radio or mobile alerts.

b. Flood Preparedness

  1. Before a Flood:

    • Know if your accommodation is in a flood-prone area (e.g., South Dunedin).
    • Keep important documents in waterproof containers.
    • Have sandbags ready if you live in a flood-prone area.
    • Monitor weather updates via MetService (New Zealandโ€™s official weather service).

  2. During a Flood:

    • Avoid walking or driving through floodwaters.
    • Move to higher ground immediately.
    • Turn off electricity and gas if instructed to do so.

  3. After a Flood:

    • Avoid contact with floodwater, as it may be contaminated.
    • Dispose of food and water that may have been affected.
    • Report damage to local authorities.

c. Landslide Preparedness

  1. Before a Landslide:

    • Avoid building or staying near steep slopes or cliffs.
    • Be aware of warning signs, such as cracks in the ground or tilting trees.

  2. During a Landslide:

    • Move away from the path of the landslide as quickly as possible.
    • If escape is not possible, curl into a tight ball to protect your head.

  3. After a Landslide:

    • Stay away from the area to avoid secondary slides.
    • Report the landslide to local authorities.

d. Tsunami Preparedness

  1. Before a Tsunami:

    • Familiarize yourself with tsunami evacuation routes (look for blue and white tsunami signs in coastal areas).
    • Know the natural warning signs: a strong earthquake, sudden sea level changes, or unusual ocean behavior.

  2. During a Tsunami:

    • If you feel a strong earthquake, immediately move to higher ground or as far inland as possible.
    • Do not wait for official warnings if natural signs are present.

  3. After a Tsunami:

    • Stay away from the coast until authorities declare it safe.
    • Be cautious of aftershocks, which could trigger additional waves.

e. Severe Weather Preparedness

  1. Before Severe Weather:

    • Secure outdoor furniture and objects that could become projectiles.
    • Keep warm clothing and blankets ready during winter storms.
    • Monitor weather updates via MetService.

  2. During Severe Weather:

    • Stay indoors and avoid unnecessary travel.
    • If driving, reduce speed and be cautious of icy or flooded roads.

  3. After Severe Weather:

    • Check for damage to your property or accommodation.
    • Avoid downed power lines and report them to authorities.
