Study Notes
Types of Volcanic Eruptions
- Phreatic Eruption: ejects a mixture of steam, water, ash, volcanic bombs, and volcanic blocks without the expulsion of new magma from the chamber
- Phreatomagmatic Eruption: an explosive eruption due to contact of water and magma, ejecting steam and pyroclastic materials
- Hawaiian Eruption: calmest type of eruption, characterized by fluid basaltic lava thrown into the air in jets from a vent or fissure at the summit or side of the volcano
- Strombolian Eruption: a type of eruption that exhibits periodic weak to violent eruption, characterized by fountain lava, and associated with ejection of incandescent dust, scoria, and volcanic bombs with little water vapor
Volcanic Hazards
- Localized landslides, rockfalls, and landslides from the summit area
- Volcanic mudflow: a mixture of volcanic debris and water that flows down the slope of the volcano
Precautionary Measures for Volcanic Eruption
- Before: be updated about the status of the volcano by listening to radio, watching TV, or browsing online news pages
- During: follow evacuation procedures and instructions from authorities
- After: be cautious of volcanic hazards such as lahars, pyroclastic flows, and ashfall
Geothermal Energy
- Definition: energy generated from the heat of the Earth's interior
- Type of energy that can be harnessed from volcanoes
- Volcanoes in the Philippines that are sources of geothermal energy
- Geothermal energy flow in a geothermal power plant
Assessment Questions
- What is the other name for Earth's internal heat? (Answer: geothermal energy)
- Which is NOT the surface manifestation of the geothermal system? (Answer: mud volcanoes)
- What do you call the geothermal element that usually occurs in the form of water or meteoric water? (Answer: geothermal fluid)
