3. Describe and relate the distribution of active volcanoes, earthquake epicenters, and major mountain belts to plate tectonic theory. At the end of this lesson, the given enabling competency should be met by the students.

4. Identify the active volcanoes in the Philippines. Determine the location and distribution of the volcanoes.

5. The movement of the crust can be caused by magma rising to Earth’s surface. Seismographs can detect this movement or deformation. This is an important tool to predict whether the volcano might erupt in the future. Review: Why is it important to monitor volcanoes?

6. Based on the Philippine Volcanic Map , each group must list active volcanoes as much as they can on their whiteboard. After 5 minutes, one group will say one active volcano that they have listed. If the opponent group has written the same volcano, both groups will cross that volcano out on their whiteboard. The process continues until one group doesn’t have any volcanoes left to say. Mapping the Volcanoes in the Philippines

7. A zone within the Pacific ocean that covers a collection of moving plate edges forming a “ring” of volcanoes that cause earthquakes . The Pacific Ring of Fire The Pacific Ring of Fire

8. A 40 000-kilometer, horseshoe-shaped basin that is associated with oceanic trenches, volcanic arcs, and plate movements. The Philippines is an archipelago surrounded by subducting plates that provides ideal condition for volcanic formation resulting in highly active seismicity and volcanism in the country. The Pacific Ring of Fire

9. Buoyant molten rock also known as magma rises toward the surface and extruded as lava during a volcanic eruption . Tectonic activity in the Philippines is one of the most active in the world characterized by a number of volcanic activities. Volcanic Activities

10. Active volcanoes are those that erupted within the last 10 000 years. As of 2008, PHIVOLCS listed 23 active volcanoes . Active Volcanoes Active volcanoes in the Philippines

11. Mayon Volcano It is the most active volcano in the country located in Albay. It is famous because of its almost perfect cone shape. Active Volcanoes Mt. Mayon

12. Taal Volcano It is a volcanic caldera composed of several active volcanic landforms making it a complex type of volcano. Active Volcanoes Taal Volcano

13. Kanlaon Volcano It is another active stratovolcano located in Negros Oriental. Its latest activity was in June 18, 2016 according to PHIVOLCS. Active Volcanoes Mt. Kanlaon

14. Bulusan Volcano It is located in the province of Sorsogon It is a stratovolcano formed inside a caldera. Its latest activity was in March 2, 2017 . Active Volcanoes Mt. Bulusan

15. Volcanoes that do not have any historical record of any eruption but are considered as morphologically young . Potentially Active Volcanoes Potentially active volcanoes Name of Volcano Province Region Nearby Cities/Towns Apo Davao XI Kidapawan, Davao City Corregidor Bataan III Mariveles Isarog Camarines Sur V Tigaon, Tinangis, Mayangayanga, Sta. Cruz, Goa, Simra, Laon, Turat, Pinaglabanan, Abucayan, Tagongtong, Buyo Lapac Sulu ARMM Siasi (Brgy. Sibaud) Malindig (Marlanga) Marinduque IV Bagacay, Lipata, Dampulan, Tigui, Malibago, Sihi Mandalagan Negros Occidental VI Bacolod City

16. Volcanoes have not erupted for at least 10 000 years and are not expected to erupt again in the future. The morphology of these volcanoes was already modified by weathering and erosion. Inactive Volcanoes

17. The Philippines is in a zone within the Pacific ocean that covers a collection of moving plate edges forming a “ring” of volcanoes and earthquakes called the Pacific Ring of Fire . As of 2008, PHIVOLCS listed 23 active, 26 potentially active and 281 inactive volcanoes .

18. Identify whether it is an active or inactive volcano. Write A for active and IA for inactive. Also identify the region/ province where the volcanoes can be found. Didicas Volcano Kanlaon Volcano Calayan Volcano Mt. Bulusan Canipo Volcano
