1. Volcanoes in the Philippines An Overview of the Most Active and Famous Volcanoes

2. Introduction The Philippines is part of the Pacific Ring of Fire, making it home to numerous active, dormant, and extinct volcanoes. Volcanoes play a significant role in the country's geography, culture, and natural hazards. Map of the Ring of Fire

3. Why Does the Philippines Have Many Volcanoes? • The Philippines lies on the Pacific Ring of Fire • Tectonic plate boundaries (Philippine Sea Plate and Eurasian Plate) • Subduction zones create conditions for volcanic activity

4. Types of Volcanoes • Stratovolcanoes – Tall, steep-sided (e.g., Mayon) • Shield Volcanoes – Broad, gently sloping (less common) • Complex Volcanoes – Combination of multiple structures

5. Famous Volcanoes in the Philippines 1. Mayon Volcano (Albay) – Known for its perfect cone shape 2. Taal Volcano (Batangas) – Small but very dangerous 3. Mount Pinatubo (Zambales) – 1991 eruption caused global cooling 4. Kanlaon Volcano (Negros) – Active volcano in Visayas 5. Bulusan Volcano (Sorsogon) – Frequently active Image of Mayon Volcano

6. Hazards of Volcanic Eruptions • Pyroclastic flows • Ashfall and lahars • Volcanic gases • Lava flows • Secondary hazards: landslides, flooding Image of Volcanic Hazards

7. Benefits of Volcanoes • Fertile soil for agriculture • Geothermal energy source • Tourist attractions • Mineral resources

8. Safety Tips During an Eruption • Follow evacuation orders • Wear masks to avoid inhaling ash • Stay indoors during ashfall • Avoid river valleys prone to lahars

9. Conclusion The Philippines' volcanoes are both a source of danger and benefit. Understanding their nature helps us prepare and coexist with these natural features.
