Volcanology

Andesite (pronunciation: /ˈændᵻsaɪt/ or /ˈændᵻzaɪt/) is an extrusive igneous, volcanic rock, of intermediate composition, with aphanitic to porphyritic texture.

Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock.

A shield volcano is a type of volcano usually built almost entirely of fluid magma flows.

Volcanic ash consists of fragments of pulverized rock, minerals and volcanic glass, created during volcanic eruptions and measuring less than 2 mm (0.079 inches) in diameter.

A pyroclastic flow (also known scientifically as a pyroclastic density current) is a fast-moving current of hot gas and rock (collectively known as tephra), which reaches speeds moving away from a volcano of up to 700 km/h (450 mph).

(Further information: Magma) Lava is the molten rock expelled by a volcano during an eruption.

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.

A volcanic field is an area of the Earth's crust that is prone to localized volcanic activity.

This article is a list of volcanic eruptions of approximately magnitude 6 or more on the Volcanic Explosivity Index (VEI) or equivalent sulfur dioxide emission during the Holocene, and Pleistocene eruptions of the Decade Volcanoes (Avachinsky-Koryaksky, Kamchatka; Colima, Trans-Mexican Volcanic Belt; Mount Etna, Sicily; Galeras, Andes, Northern Volcanic Zone; Mauna Loa, Hawaii; Mount Merapi, Central Java; Mount Nyiragongo, East African Rift; Mount Rainier, Washington; Sakurajima, Kagoshima Prefecture; Santamaria/ Santiaguito, Central America Volcanic Arc; Santorini, Cyclades; Taal Volcano, Luzon Volcanic Arc; Teide, Canary Islands; Ulawun, New Britain; Mount Unzen, Nagasaki Prefecture; Mount Vesuvius, Naples); Campania, Italy; South Aegean Volcanic Arc; Laguna de Bay, Luzon Volcanic Arc; M

Gregoryite is an anhydrous carbonate mineral that is rich in potassium and sodium with formula: [(Na2,K2,Ca)CO3].

Journal of Volcanology and Geothermal Research is a scientific journal that publishes recent research on the fields of volcanology and geothermal activity.

The International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) is a learned society that focuses on research in volcanology, efforts to mitigate volcanic disasters, and research into closely related disciplines, such as igneous geochemistry and petrology, geochronology, volcanogenic mineral deposits, and the physics of the generation and ascent of magmas in the upper mantle and crust.

Pumice (pronunciation: /ˈpʌmᵻs/), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals.

The Finlay tephras is the term for two tephra deposits in northern British Columbia, Canada.

The Northern Cordilleran Volcanic Province (NCVP), formerly known as the Stikine Volcanic Belt, is a geologic province defined by the occurrence of Miocene to Holocene volcanoes in the Pacific Northwest of North America.

Michael Wutky (1739, Krems an der Donau - 28 September 1822/23, Vienna) was an Austrian landscape painter in the Rococo style who specialized in Italian scenes.

The National Institute for Seismology, Vulcanology, Meteorology and Hydrology of Guatemala (in Spanish: Instituto Nacional de Sismología, Vulcanología, Meteorología e Hidrología (INSIVUMEH)) is a scientific agency of the Guatemalan government.

A subaqueous volcano is a volcano formed beneath freshwater and never builds above lake level.

Volcano House is a Geology exhibition in Reykjavík, Iceland, located at Tryggvagata 11.

A rift zone is a feature of some volcanoes, especially shield volcanoes, in which a linear series of fissures in the volcanic edifice allows lava to be erupted from the volcano's flank instead of from its summit.

Below is a list of new islands created since the beginning of the 20th century whether by means of volcanism, erosion, glacial retreat, or other mechanisms.

The Bulletin of Volcanology is a peer reviewed scientific journal that is published ten times per year by Springer Science+Business Media.

Prediction of volcanic eruption (also: volcanic eruption forecasting) is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption.

Sheep Track Pumice or Sheep Track Member by Canadian volcanologist Jack Souther, is the name for a pumice deposit in northern British Columbia, Canada.
