1. According to PHIVOLCS there were 26 active volcanoes in the Philippines.
2. The Phreatomagmatic eruption is a stream-driven eruption as hot rocks come in contact with water
3. Active volcanoes are those that have a record of eruption within the last 600 years or those that have erupted 10,000 years ago based on analyses of their material.
4. In geothermal power plants, the heat from deep inside the Earth is used to produce steam to generate clectricity
S. Volcanic eruption can increase the earth's temperature and can cause global warming.
6. The heat from the Earth's interior is a source of energy called geothermal energy.
7. According to the Department of Energy, 30% of the country's total power generation is produced from geothermal energy.
8. Vulcanian is characterized by tall eruption columns that reach up to 20 km high with pyroclastic flow and ashfall tephra like that of Paricutin Volcano in Mexico.
9. Volcanoes erupt when magma and pressure come together, and the pressure blows off the top of the solid rock, and the magma pours out.
10. Phreatic eruption is an excessively explosive type of eruption of gas and pyroclastic.
