    Study Notes

    Disaster Readiness and Risk Reduction Overview

    • Sudden movements of the Earth’s crust lead to earthquakes, causing ground shaking, soil liquefaction, landslides, and tsunamis.
    • Volcanic eruptions result in the expulsion of gases, ash, and molten lava from the Earth.

    Types of Hazards

    • Hydrometeorological Hazards: Includes tropical cyclones (also known as typhoons) characterized by severe winds, heavy rainfall, storm surges, floods, and lightning.
    • Flooding: Involves overflow of water onto dry land, potentially leading to significant destruction.
    • Drought: Prolonged dry periods resulting in water shortages, impacting health and agriculture.

    Disaster Risk Factors

    • Biological Factors: Flora, fauna, and the prevalence of infectious diseases in densely populated areas heighten vulnerability.
    • Psychological Factors: Mental health conditions, such as anxiety and depression, can impair the ability to respond to disasters.
    • Economic Factors: Damage to essential economic activities can deplete resources and reduce recovery capacity.
    • Political Factors: Disasters can prompt governance changes and reveal flaws in civil society structures.
    • Sociocultural Factors: Community beliefs and practices influence disaster preparedness and response strategies.

    Earthquakes

    • Earthquakes result from the sudden energy release in the Earth's crust, causing seismic waves and shaking.
    • Most earthquakes occur along tectonic plate boundaries.

    Measuring Earthquakes

    • Risk levels are categorized by ground shaking intensity:
      • Yellow/Orange zones indicate moderate to high risks, with the potential for damage to poorly constructed buildings.
      • Red zones signify high risks of severe damage, including total destruction in areas near major faults.

    Mitigation Strategies

    • Preparedness: Understand local disaster risks and assess home structural integrity; retrofit structures as necessary.
    • Response: Make noise for help if trapped; use cell phones cautiously; check for injuries and hazards upon escape.
    • Rehabilitation: Seek medical assistance for injuries and report sinkholes to authorities.
    • Volcanic Eruptions: Cause asphyxiation, burns, and dynamic pressure-related injuries from hot ash and gases.
    • Lahars: Mudflows consisting of volcanic material and water can bury infrastructure and communities.
    • Ashfall: Volcanic particles can lead to agricultural losses and pose health risks due to airborne particles.

    Alert Levels of PHIVOLCS

    • Alert Level 0: No alerts indicate normal conditions.
    • Alert Level 1: Signs of abnormal activity with low seismic activity, no imminent eruption.
    • Alert Level 2: Increasing unrest with heightened volcanic activity and potential for eruption.

    Environmental Impacts

    • Volcanic activities can lead to melted landscapes, vegetation drying up, and significant changes in nearby water sources.
    • New thermal areas may form or existing ones reactivate, impacting local ecosystems.
