Natural Hazards in Wellington
Wellington is located on the southern tip of New Zealand's North Island, along a tectonic plate boundary. This makes it prone to several natural hazards, including:
- Earthquakes
- Tsunamis
- Severe Weather (Windstorms and Heavy Rain)
- Landslides
- Flooding
1. Earthquakes
Why Itโs a Risk:
- Wellington lies on the Pacific Ring of Fire and is near the Wellington Fault, making it highly seismically active.
- Earthquakes can range from minor tremors to major quakes capable of causing significant damage.
Safety Procedures:
- 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.
- After an Earthquake:
- Be prepared for aftershocks.
- Check for injuries and hazards like gas leaks or damaged electrical lines.
- Follow local emergency services' instructions.
Preparedness Tips:
- Secure heavy furniture and appliances to walls.
- Keep an emergency kit with food, water, a flashlight, batteries, a first aid kit, and essential documents.
- Know the location of your nearest Civil Defence Centre (emergency shelters).
Local Sites to Avoid During Emergencies:
- High-rise buildings and older structures that may not be earthquake-resistant.
- Areas near cliffs or steep hillsides prone to landslides.
2. Tsunamis
Why Itโs a Risk:
- Earthquakes in the Pacific Ocean or along the Hikurangi Subduction Zone can trigger tsunamis.
- Wellingtonโs coastal location makes it vulnerable to tsunami waves.
Safety Procedures:
- During a Tsunami Warning:
- If you feel a long or strong earthquake (lasting more than a minute or very intense), move to higher ground immediately.
- Follow official tsunami evacuation routes marked in the city.
- Do not wait for an official warning if you are near the coast and feel a strong earthquake.
- After a Tsunami:
- Stay away from the coast until authorities declare it safe.
- Avoid returning to low-lying areas too soon, as multiple waves may occur.
Preparedness Tips:
- Familiarize yourself with tsunami evacuation zones and routes (maps are available online and in public spaces).
- Practice evacuation drills with your family or household.
- Keep a "grab bag" with essentials ready to go.
Local Sites to Avoid During Emergencies:
- Low-lying coastal areas such as Oriental Bay, Lyall Bay, and the Wellington waterfront.
3. Severe Weather (Windstorms and Heavy Rain)
Why Itโs a Risk:
- Wellington is known as the "Windy City" due to its strong winds, especially during storms.
- Heavy rain can lead to localized flooding and landslides.
Safety Procedures:
- During Severe Weather:
- Stay indoors and avoid unnecessary travel.
- Secure outdoor furniture and objects that could become projectiles in high winds.
- Avoid walking or driving through floodwaters.
- After Severe Weather:
- Check for damage to your property and report any hazards to local authorities.
- Avoid areas with downed power lines or unstable trees.
Preparedness Tips:
- Monitor weather forecasts through MetService (New Zealandโs official weather service).
- Ensure your home is well-maintained to withstand strong winds and heavy rain.
- Have sandbags ready if you live in a flood-prone area.
Local Sites to Avoid During Emergencies:
- Flood-prone areas such as the Hutt Valley and low-lying parts of the CBD.
- Exposed coastal areas during storms.
4. Landslides
Why Itโs a Risk:
- Wellingtonโs hilly terrain and frequent rain make it susceptible to landslides, especially after heavy rainfall or earthquakes.
Safety Procedures:
- During a Landslide:
- Move away from the path of the slide if possible.
- If indoors, take cover under sturdy furniture and stay away from windows.
- After a Landslide:
- Avoid the area as it may still be unstable.
- Report landslides to local authorities.
Preparedness Tips:
- Avoid building or living near steep slopes or cliffs.
- Plant vegetation to stabilize soil on your property.
- Be alert to warning signs like cracks in the ground or tilting trees.
Local Sites to Avoid During Emergencies:
- Steep hillsides and areas with loose soil, such as parts of Ngaio Gorge and Wadestown.
5. Flooding
Why Itโs a Risk:
- Heavy rain can overwhelm Wellingtonโs drainage systems, leading to flash flooding.
- Low-lying areas and riverbanks are particularly vulnerable.
Safety Procedures:
- During a Flood:
- Move to higher ground immediately.
- Avoid walking or driving through floodwaters, as they can be deeper and faster-moving than they appear.
- After a Flood:
- Avoid contact with floodwater, as it may be contaminated.
- Check your property for damage and report hazards.
Preparedness Tips:
- Ensure your homeโs drainage systems are clear and functioning.
- Store valuables and important documents in waterproof containers.
- Purchase flood insurance if you live in a high-risk area.
Local Sites to Avoid During Emergencies:
- Low-lying areas such as the Hutt Valley, Kilbirnie, and parts of the CBD.
Costs and Resources for Managing Hazards
Costs:
- Emergency Kits: Pre-made kits cost around NZD 100โ300, or you can assemble your own.
