Study Notes
Philippine Volcanoes
- The Philippines is an archipelago with over 7100 islands, most volcanically-originated.
- There are approximately 390 volcanoes, 23 active and the rest dormant.
- Famous volcanoes include Mount Pinatubo, Mount Mayon and Taal Volcano, all located in Luzon.
- The Philippines sits on the Pacific Ring of Fire, where the Philippine tectonic plate and several smaller plates are subducting along the Philippine Trench (east and Luzon, Sulu, and western trenches.)
- The tectonic setup features small plates squeezed between convergent plate margins, separated by small subduction zones and major faults.
- Philippine volcanoes form at the junction of the Philippine and Eurasian plates.
- Volcanic eruptions are historically deadly and costly.
- About 13% historic eruptions resulted in casualties (e.g., Taal, Mayon, Pinatubo).
- 22% of historic eruptions also caused significant damage.
- Lahars (mudflows) are common due to frequent heavy rains.
- Tsunamis frequently accompany eruptions.
- PHIVOLCS (Philippine Institute of Volcanology and Seismology) monitors volcanic activity.
