Study Notes
Natural Hazards and Disasters
- A natural hazard is a natural event or phenomenon that has the potential to cause harm to people and their environment.
Geophysical Systems
- Geophysical systems provide people with opportunities and constraints.
Perceived Normal Events
- People perceive earthquakes, volcanic eruptions, and storms as 'normal events' within the geophysical systems.
Ecological Hazards
- Ecological hazards involve the effects of human activities on the environment, such as pollution, deforestation, and climate change.
- Ecological hazards are the result of human interference with the natural environment.
Natural Hazards vs. Disasters
- In the absence of people, natural hazards are just natural events.
- An event becomes a disaster when it affects human populations and causes harm.
Disaster Classification
- According to the UN's International Strategy for Disaster Reduction, a disaster occurs when a hazard affects a vulnerable population, resulting in damage, loss, and disruption.
Hazards vs. Disasters
- The main difference between a hazard and a disaster is the presence of people and the resulting harm.
Natural Hazards
- Tropical storms, floods, landslides, droughts, bushfires, earthquakes, and volcanoes are all natural hazards.
- Tropical storms are most likely to occur in areas between the equator and the tropics of Cancer and Capricorn.
- Landslides are most likely to occur in areas with steep slopes and heavy rainfall.
- Floods are responsible for 4500 deaths per year and affected 4.8 million people between 1998 and 2017.
- Earthquakes are characterized by the sudden movement and shaking on the earth's surface.
Regional Hazards
- Infectious diseases such as Ebola are most predominantly distributed in tropical regions.
- Over 500 active volcanoes are mainly concentrated in the Pacific Ring of Fire.
- The ring of fire is located around the Pacific Ocean, where a significant proportion of the world's largest earthquakes occur.
Bushfires
- The main feature of a bushfire is the rapid spread of fire through dry vegetation, often fueled by strong winds.
