Disaster Readiness and Risk Reduction Overview

  • Opening Prayer: Acknowledgement of divine guidance during learning at ACTS Computer College.

  • Course Focus: Disaster Readiness and Risk Reduction with an emphasis on understanding hazards.

  • Objective: Students should be able to:

    • Identify effects of major earthquake hazards.
    • Relate these effects to various earthquake hazards.
    • Explain earthquake-related impacts on the community.

  • Understanding Earthquakes:

    • Definition: Ground shaking caused by sudden rock displacement.
    • Types:
    • Tectonic: Movement along faults in the earth's rigid layers.
    • Volcanic: Caused by rising lava/magma beneath volcanoes.

  • Faults:

    • Characteristics:
    • A fracture or weakness zone where displacement occurs or can occur.
    • Evidence of seismic activity or movement in the last 10,000 years categorized as Active Fault.

  • Earthquake-Related Hazards:

    • Ground Shaking: Upward and sideways motion during earthquakes.
    • Ground Rupture: Displacement on the ground aligned with fault movement.
    • Tsunami: Sea waves generated by disturbances in the ocean floor.
    • Liquefaction: Transformation of solid sediments into liquid due to intense shaking.
    • Earthquake-Induced Landslides: Movement of ground materials triggered by seismic activity.

  • Recovery Strategies: Approaches to recover from earthquakes and related hazards.

  • Closing Remarks: A note of gratitude and safety wishes to students.
