    Study Notes

    Hazards and Disasters

    • Natural hazards are naturally occurring events that can cause damage or loss of life, whereas technological (man-made) hazards are caused by human error or failure of infrastructure.
    • Human intervention can increase the frequency and severity of natural hazards by activities such as deforestation, land degradation, and climate change.

    Earthquakes

    • Ground shaking during an earthquake is affected by factors such as the magnitude of the earthquake, distance from the epicenter, and type of soil or rock.

    Tsunamis

    • A tsunami is a series of ocean waves that are triggered by the displacement of a large volume of water, usually as a result of an earthquake or landslide.

    Disaster Risk Reduction

    • The main purpose of the text is to understand and address the risks associated with natural and man-made hazards.
    • A 'hazard' is defined as a situation or event that has the potential to cause harm or damage.
    • Exposure refers to the people, property, and infrastructure that are in the path of a hazard.
    • Capacity refers to the ability of individuals, communities, and societies to cope with and recover from disasters.
    • Hazards and human intervention are interrelated, as human activities can increase the risk of natural hazards.

    Vulnerability

    • Vulnerability is the susceptibility of individuals, communities, and societies to be affected by hazards.
    • Physical vulnerability refers to the risk of physical harm or damage to infrastructure.
    • Social vulnerability focuses on the social and economic factors that affect the ability of individuals and communities to cope with disasters.
    • Environmental vulnerability refers to the impact of natural hazards on the environment.

    Disaster Management

    • The primary objective of emergency response efforts is to save lives and reduce suffering.
    • Disaster risk reduction involves identifying and mitigating the risks associated with hazards, and building capacity to cope with and recover from disasters.

    Causes of Disasters

    • Geological causes of disasters include earthquakes, landslides, and volcanic eruptions.
    • Human causes of disasters include human error, conflict, and environmental degradation.
    • Morphological causes of disasters include the shape and features of the land.
