Natural Hazards and Disasters

Awareness of potential natural disasters such as bushfires, floods, or storms, and how to stay prepared and informed.

Sections

1. Bushfires

Overview:

Canberra is surrounded by bushland and grasslands, making it prone to bushfires, particularly during the hot, dry summer months (December to February). The 2003 Canberra bushfires were a significant event, causing widespread damage and loss of life.

Potential Impacts:

  • Human Safety: Risk of injury or loss of life.
  • Property Damage: Destruction of homes, infrastructure, and natural habitats.
  • Air Quality: Smoke from bushfires can cause respiratory issues.
  • Economic Costs: Recovery and rebuilding efforts can be expensive.

Preparation Protocols:

  • Bushfire Survival Plan: Residents are encouraged to create a bushfire survival plan, detailing evacuation routes and safety measures.
  • Property Maintenance: Clear gutters, remove flammable materials, and maintain a defensible space around homes.
  • Emergency Kits: Prepare kits with essentials like water, food, first aid supplies, and important documents.
  • Stay Informed: Monitor the ACT Emergency Services Agency (ESA) website and the Fires Near Me app for updates.

Associated Costs:

  • Preparation Costs: Clearing vegetation, installing fire-resistant materials, and purchasing emergency kits can cost between AUD 500โ€“2,000.
  • Response Costs: Evacuation and temporary accommodation may add to expenses.
  • Insurance: Home insurance premiums may increase in bushfire-prone areas.

Local Considerations:

  • The ACT Emergency Services Agency (ESA) provides bushfire warnings and preparedness resources.
  • The Bushfire Ready Neighbourhoods program offers community workshops and information sessions.

2. Severe Storms and Hail

Overview:

Canberra experiences severe thunderstorms, particularly in spring and summer. These storms can bring heavy rain, strong winds, hail, and lightning.

Potential Impacts:

  • Property Damage: Hail can damage roofs, cars, and crops.
  • Flooding: Intense rainfall can lead to flash flooding in low-lying areas.
  • Power Outages: Storms can disrupt electricity and communication networks.

Preparation Protocols:

  • Secure Property: Trim overhanging branches, secure outdoor furniture, and ensure roofs are in good condition.
  • Flood Preparedness: Avoid driving or walking through floodwaters and know the location of higher ground.
  • Emergency Alerts: Sign up for weather alerts from the Bureau of Meteorology (BOM).

Associated Costs:

  • Preparation Costs: Installing storm shutters, maintaining drainage systems, and purchasing insurance can cost AUD 1,000โ€“5,000.
  • Response Costs: Repairs to property and vehicles can be significant, depending on the severity of the storm.

Local Considerations:

  • The ACT State Emergency Service (SES) provides assistance during storms and floods, including sandbagging and emergency repairs.
  • The BOM issues weather warnings and forecasts.

3. Earthquakes

Overview:

Earthquakes in Canberra are rare and typically minor. However, the region is not entirely free from seismic activity.

Potential Impacts:

  • Structural Damage: Older buildings may be more vulnerable to damage.
  • Disruption: Minor tremors can cause temporary disruptions to services.

Preparation Protocols:

  • Building Standards: Ensure homes and buildings comply with modern earthquake-resistant standards.
  • Emergency Plans: Know safe spots in your home (e.g., under sturdy furniture) and practice "Drop, Cover, and Hold" drills.

Associated Costs:

  • Preparation Costs: Retrofitting older buildings can cost AUD 5,000โ€“20,000.
  • Response Costs: Repairs after an earthquake are typically minimal in Canberra due to the low risk.

Local Considerations:

  • Earthquake risk is low, but the Geoscience Australia website provides information on seismic activity.

4. Heatwaves

Overview:

Canberra experiences heatwaves during summer, with temperatures often exceeding 40ยฐC (104ยฐF). Heatwaves are becoming more frequent and intense due to climate change.

Potential Impacts:

  • Health Risks: Heat exhaustion, dehydration, and heatstroke, particularly for vulnerable populations (e.g., elderly, children).
  • Infrastructure Strain: Increased demand for electricity can lead to power outages.
  • Environmental Impact: Stress on water resources and vegetation.

Preparation Protocols:

  • Stay Hydrated: Drink plenty of water and avoid alcohol or caffeine.
  • Stay Cool: Use fans or air conditioning, and avoid outdoor activities during peak heat.
  • Check on Vulnerable People: Ensure elderly neighbors or relatives are safe.
  • Emergency Alerts: Monitor heatwave warnings from the BOM.

Associated Costs:

  • Preparation Costs: Installing air conditioning or fans can cost AUD 1,000โ€“5,000.
  • Response Costs: Increased electricity bills during heatwaves.

Local Considerations:

  • The ACT Government provides heatwave advice and cooling centers during extreme heat events.

5. Flooding

Overview:

While Canberra is not prone to large-scale river flooding, flash flooding can occur after heavy rainfall, particularly in urban areas with poor drainage.

Potential Impacts:

  • Property Damage: Floodwaters can damage homes, vehicles, and infrastructure.
  • Safety Risks: Driving or walking through floodwaters can be life-threatening.

Preparation Protocols:

  • Flood Insurance: Ensure your property is covered for flood damage.
  • Drainage Maintenance: Keep gutters and drains clear to reduce the risk of water pooling.
  • Emergency Plans: Know evacuation routes and have a plan for moving to higher ground.

Associated Costs:

  • Preparation Costs: Installing flood barriers or improving drainage can cost AUD 1,000โ€“10,000.
  • Response Costs: Repairs and cleanup after flooding can be expensive, depending on the severity.

Local Considerations:

  • The ACT SES provides flood warnings and assistance during emergencies.
  • The BOM issues flood alerts and rainfall forecasts.

6. Wildlife Encounters

Overview:

Canberraโ€™s proximity to bushland means encounters with wildlife, including snakes, kangaroos, and spiders, are possible.

Potential Impacts:

  • Health Risks: Snake or spider bites can be dangerous if untreated.
  • Vehicle Collisions: Kangaroos are often seen on roads, particularly at dawn and dusk.

Preparation Protocols:

  • First Aid Knowledge: Learn basic first aid for bites and stings.
  • Drive Safely: Be cautious when driving in areas with wildlife.
  • Secure Homes: Seal gaps to prevent spiders or snakes from entering.

Associated Costs:

  • Preparation Costs: First aid kits and training may cost AUD 100โ€“500.
  • Response Costs: Medical treatment for bites or stings may be covered by Medicare or private health insurance.

Local Considerations:

  • The ACT Government provides advice on living with wildlife and managing encounters.
