    Study Notes

    Disaster Basic Concepts

    • A disaster is a sudden calamitous occurrence that causes significant harm, injury, destruction, and life-threatening situations, leading to physical and emotional stress.
    • Examples of natural disasters include earthquakes, typhoons, volcanic eruptions, hurricanes, fires, tornadoes, and extreme temperatures.

    Hazard and Risk

    • A hazard is anything that can cause harm to human life, including injury, illness, property damage, and environmental damage.
    • A natural hazard occurs when an extreme natural event is destructive to human life and property, such as strong winds, hail, coastal flooding, and landslides.
    • A human-made hazard, on the other hand, is caused by human activities, such as terrorism.
    • Risk is the combination of the probability of an event and its negative consequences.

    Disaster Risk Reduction

    • Disaster risk is the potential for disaster losses in lives, health status, livelihoods, assets, and services.
    • Capacity refers to the combination of community, societal, or organizational strengths that aid in coping with or resisting hazard impact.
    • Disaster preparedness involves developing plans and allocating resources to save lives and prevent property damage.

    Vulnerability

    • Exposure refers to the probability of varying hazard events.
    • Vulnerability is a system or asset's susceptibility to damaging effects of a hazard, influenced by characteristics and circumstances of a community, such as poor location or community conflict.

    Disaster Types

    • Landslide, also known as land slip, is a geological phenomenon involving ground movements.
    • Area with armed conflicts often involves combat or warfare with continual violence involving armed groups or military forces.

    Earthquake Hazards

    • Ground displacement is the deformation of the ground.
    • Ground shaking is the vibration of the ground.
    • Landslide is the down-slope movement of rocks, soil, and debris.
    • Tsunami is a series of huge waves.
    • Liquefaction is the saturation of soil with groundwater, requiring three factors: loose, granular sediment; water-saturated sediments; and strong shaking.

    Volcanic Hazards

    • Ashfall is volcanic ash consisting of tiny jagged particles of rocks.
    • Volcanic gases include water vapor and other gases such as CO2, H2S, SO2, and HCl.
    • Lava flow is a stream of molten rock that flows out of the volcano.
    • Pyroclastic flow is a fluidized mass of rock fragments and gases that move rapidly due to gravity.
    • Lahar flow is a mudflow or debris flow composed of mostly volcanic materials mixed with water.

    Impacts of Disaster

    • Physical impacts include injury or death.
    • Psychological impacts include panic or distress, leading to trauma.
    • Socio-cultural impacts can alter public perception about the ability and concern of political players, leading to changes in individual roles.
    • Political impacts can open opportunities for politicians to gain advantage.
    • Economic impacts include loss of skilled workers.

    Severity of Disaster

    • Education, wealth, governance, technology, and age influence the severity of disaster.
    • Economic status of the country can influence the effect of the impact of disaster.

    Factors Underlying Disasters

    • Climate change, environmental degradation, globalized economic development, poverty, and inequality contribute to disasters.
    • Poorly planned and managed urban development, weak governance, and geographical location also contribute to disasters.

    Effects of Disaster on One's Life

    • Displaced population: people abandon their homes and seek shelter in other regions.
    • Health risks include physical injury, respiratory issues, and contaminated food.
    • Food security is threatened, leading to food shortage and loss of livelihood.
    • Emotional aftershocks include extreme trauma and PTSD.
