Volcano - opening in the planet’scrust through which molten rock,hot gases, and other materialserupt.
Volcano - form a hill or mountain as layers of rock and ash build-up from repeated eruptions
Volcanologist - A volcano scientist is a geologist who studies the formation and eruptive activity of volcanoes.
Volcanology is the study of volcanoes
Philippine Institute of Volcanology and Seismology (PHIVOLCS) - mitigating disasters from volcanic eruptions, earthquakes, tsunamis, and related geotectonic phenomena
MAGMA CHAMBER - A reservoir where magma is stored beneath the volcano.
SILL - Flat rock formation that forms when molten magma cools and solidifies
LAVA FLOW - Molten rock that flows from a volcano during an eruption
CONDUIT - A pipe-like structure that connects the magma chamber to the surface
CONE - Steep,conical-shaped hill or mountain formed by layers of volcanic material
Active Volcano - eruption within the last 600 years
There are 24 active volcanoes in the Philippines
Mt. Mayon is the most active volcano in the Philippines
Taal is the second most active volcano in the Philippines
Mt. Kanlaon is the third most active volcano in the Philippines
Potentially Active - Morphologically young-looking but with no historical or analytical records of eruption.
Mt. Apo, Mt. Arayat, Mt. Labo are potentially active volcanoes in the Philippines
Mt. Balungao, Mt. Batulao, Mt. Pan de Azucar are inactive volcanoes in the Philippines
Some of the grandest volcanoes are composite volcanoes / stratovolcanoes
Cinder Cone Volcano are built from ejected semisolid lava
Cinder cone volcano have circular or oval cones and are not very tall
Shield Volcano resembles a dome
Volcanism is the eruption of molten rock from inside the Earth to the surface
MAGMA - • Hot fluid or semi-fluid material beneath the crust of the earth.
All of the magma is created in the asthenosphere. The magma slowly rises through the lithosphere. It rises because it is hot, less dense, and because of the increased pressure below
The higher the silica content, the more viscous the magma is
The more water content, the more gases expand, and the more explosive the eruption
Once magma is ejected from the volcanic vents and flows on the surface, it is called lava
Lava viscosity is influenced by temperature, mineral, and water content.
Pyroclastic flows consist of a mixture of volcanic gases and ash
Ashfall - finer ejected materials carried away by the wind
LAHAR - hot or cold mixture of water and rockfragments that flows down the slopes ofa volcano and typically enters a rivervalley. A result of heavy rainfall duringor after the eruption
Geothermal energy - A renewable energy source produced from the heat inside Earth that can be harvested for human u
Tiwi geothermal power plant - located at Mt. Malinao in theProvince of Albay. Operations started in May 1979
The Makiling-Banahaw (Makban Geothermal Power Plant) Geothermal power plant in South Luzon is one of the 20 power plants completed during the Marcos administration.
Bac-Man Geothermal Power Plant is operated by Energy Development Corporation in the provinces of Albay and Sorsogon in the Philippines. It is named for its location in the municipalities of Bacon and Manito
Palinpinon Geothermal Power Plant is a 192.5-MW complex of geothermal power stations in Valencia, Negros Oriental
Binary Cycle Power plant - Hot water is pumped through a heatexchanger heating a second liquid to turn into steam
