Ecological and Natural hazard examples

• Tropical storms/cyclones:

  • aka hurricanes or typhoons depending on the location
  • intense circular storms
  • e.g. cyclone Yasi, Queensland 2011
• Floods:

  • induction of water in a normally dry area of land
  • can be caused by the overflow of inland or tidal water or runnoff of surface waters generally due to heavy rainfall
  • e.g. 2019-2011 Brisbane and Queensland floods
• Landslides:

  • movement of mass rock, soil and debris down a slope under the influence of gravity
  • e.g. the Vargas tragedy 1999
• Droughts:

  • a deficiency of rainfall substantially below the average experiences in a location over an extended period.
  • can contrinue for a season of over several years
  • e.g. Australian drought 2017-2020
• Bushfires:

  • uncontrolled burning of nature which threaters property, life and the environment
  • e.g. 2009 black saturday fires
• Earthquakes:

  • seismic waves of energy radiating from faults in all directions resulting in violent shacking of earths surface
  • significant hazard to communities esspecially ones located on tectonic plate boundaries
  • e.g. 2011 Tohoku Japan earthquake
• Volcanoes:

  • vents from earths surface that allows for magma to escape from interior, causing eruption of lava and gaz into atmosphere
  • e.g. Mt Pinatubo 1991
• Infectiouse disease:

  • describes diseases that can spread from one person to another either directly or indirectly.
  • e.g. HIV/AIDS in East and Southern Africa
• Animal transmitted diseases:

  • subcategory of infectious disease, can also be referred to as vectorborne diseases, transmitted to humans from animals.
  • e.g. rabies in Australia
• Water bourne deases:

  • subcatagory of infectiouse disease caused bt microorganism (such as bacteria, virusus, protoza, parasites) contaminating the water
  • e.g. Yemen choloera crisis 2019
• Animal invasions:

  • animals not native to a specific ecosystem, there introduction tends to cause harm to the environment, economy, or human health
  • e.g. cane toads in Australia
• Chemical hazard:

  • incidents being caused by a toxic substance which can cause harm to people and the environment
  • e.g. 2010 deepwater horizon oil spill
