Perth

1. Overview of Natural Hazards in Perth

Perth and its surrounding regions are susceptible to several natural hazards, including:

a. Bushfires

• Risk: Perth experiences hot, dry summers, making bushfires a significant risk, particularly in the outer suburbs and rural areas with dense vegetation.
• High-Risk Areas: The Perth Hills, Darling Scarp, and areas with large bushland reserves (e.g., Kings Park, Yanchep National Park).
• Season: Bushfire season typically runs from November to April.

b. Heatwaves

• Risk: Perth is known for its extreme summer temperatures, often exceeding 40°C (104°F). Prolonged heatwaves can pose health risks, especially to the elderly, children, and those with pre-existing conditions.
• Season: Summer (December to February).

c. Severe Storms

• Risk: Perth can experience severe thunderstorms, particularly in spring and summer. These storms may bring heavy rainfall, strong winds, hail, and lightning.
• Season: October to April.

d. Flooding

• Risk: While Perth is generally dry, heavy rainfall during storms can lead to flash flooding in low-lying areas or poorly drained urban zones.
• High-Risk Areas: Suburbs near the Swan River, Canning River, and other waterways.

e. Earthquakes

• Risk: Western Australia is seismically active, and while large earthquakes are rare, minor tremors can occur. The Meckering earthquake of 1968 (magnitude 6.5) is a historical example of the region's seismic potential.
• High-Risk Areas: Perth itself is considered low-risk, but areas further inland, such as the Wheatbelt region, are more prone to seismic activity.

f. Coastal Hazards

• Risk: Perth’s coastline is subject to erosion, strong currents, and occasional storm surges. Swimmers and beachgoers should be cautious of rips and changing tides.
• High-Risk Areas: Beaches like Cottesloe, Scarborough, and Trigg.

2. Safety Measures to Take

To stay safe from natural hazards in Perth, follow these guidelines:

a. Bushfires

• Preparation:
  • If living near bushland, create a bushfire survival plan and maintain a defensible space around your property (e.g., clear vegetation, store flammable materials away from the house).
  • Install fire-resistant roofing and ember guards.
  • Stay informed via the Department of Fire and Emergency Services (DFES) website or the Emergency WA app.
• During a Bushfire:
  • Follow evacuation orders immediately.
  • If caught in a fire, seek shelter in a cleared area or a solid structure.
  • Wear protective clothing (long sleeves, sturdy shoes) and cover your face with a damp cloth.

b. Heatwaves

• Preparation:
  • Stay hydrated and avoid outdoor activities during peak heat (10 a.m. to 4 p.m.).
  • Ensure your home has adequate cooling (air conditioning or fans).
  • Check on vulnerable individuals (elderly, children, pets).
• During a Heatwave:
  • Seek shade or air-conditioned spaces (e.g., shopping malls, libraries).
  • Wear lightweight, loose-fitting clothing and use sunscreen.

c. Severe Storms

• Preparation:
  • Secure outdoor furniture and loose items to prevent them from becoming projectiles.
  • Trim overhanging branches near your home.
  • Ensure your roof and gutters are in good condition to handle heavy rain.
• During a Storm:
  • Stay indoors and away from windows.
  • Avoid using electrical appliances during lightning storms.
  • Do not drive through flooded roads.

d. Flooding

• Preparation:
  • Know the flood risk in your area by checking local flood maps.
  • Elevate valuable items and electrical appliances if flooding is forecast.
• During a Flood:
  • Avoid walking or driving through floodwaters (as little as 15 cm of water can sweep a car away).
  • Move to higher ground if necessary.

e. Earthquakes

• Preparation:
  • Secure heavy furniture and appliances to walls.
  • Identify safe spots in your home (e.g., under sturdy tables or door frames).
• During an Earthquake:
  • Drop, cover, and hold on. Stay indoors until the shaking stops.
  • If outdoors, move away from buildings, trees, and power lines.

f. Coastal Hazards

• Preparation:
  • Swim only at patrolled beaches and between the red and yellow flags.
  • Check weather and tide conditions before heading to the beach.
• During a Coastal Emergency:
  • Follow lifeguard instructions and evacuation orders.
  • Avoid entering the water during storm surges or high tides.
