Disaster Readiness and Risk Reduction - Volcanic Hazards

  • Opening Prayer: Invocation for guidance and wisdom through the Holy Spirit.

  • ACTS Computer College Overview: Located in Sta. Cruz, Laguna, established in 1987.

  • Subject Focus: Disaster Readiness and Risk Reduction, with emphasis on volcanic and earthquake-related hazards.

  • Learning Objectives:

    • Explain volcano-related hazards.
    • Identify common volcano-related hazards in the Philippines.
    • Examine the effects of volcanic hazards on life.

  • Types of Volcanic Hazards:

    • Lava Flows:
    • Hot melted rock, moves slowly, creates new land, can burn and bury.
    • Ashfall (Tephra Fall):
    • Airborne particles causing breathing difficulty, roof collapse, damage to crops, and air pollution.
    • Pyroclastic Flows:
    • Fast-moving hot gas and fragmented materials, destructive with temperatures above 1000 °C.
    • Lahars:
    • Mixture of volcanic ash and water, can bury and sweep away properties.
    • Volcanic Gases:
    • Emissions like sulfur dioxide creating breathing problems, especially in low-lying areas.
    • Volcanic Landslide:
    • Caused by collapse due to eruptions or earthquakes.
    • Tsunami:
    • Generated by sudden water displacement, poses risks to coastal areas.

  • Activity:

    • Analyze impacts of specific volcanic hazards on the six most active volcanoes in the Philippines (Pinatubo, Taal, Mayon, Bulusan, Kanlaon, Hibok-hibok).

  • Conclusion: Recap of hazards discussed, safety reminders, and a closing prayer expressing gratitude.
