    Augustine Volcano (Alaska) during its eruptive phase on January 24, 2006. A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

    en.wikipedia.org/wiki/Volcanology

    Compositional analysis has been very successful in the grouping of volcanoes by type, [9]: 274 origin of magma, [9]: 274 including matching of volcanoes to a mantle plume of a particular hotspot, mantle plume melting depths, [10] the history of recycled subducted crust, [9]: 302–3 matching of tephra deposits to each other and to volcanoes of ...

  4. Prediction of volcanic activity - Wikipedia

    en.wikipedia.org/wiki/Prediction_of_volcanic...

    The volcano made up for this decrease in magma by retrieving more magma from its storage zone to bring up to the upper levels of the plumbing system. Due to this retrieval, it led to an eruption. The microgravity studies that were performed by this team shows the migration of magma and gas within a magma chamber prior to any eruption, which can ...

  5. Types of volcanic eruptions - Wikipedia

    en.wikipedia.org/wiki/Types_of_volcanic_eruptions

    Volcanoes are not bound to one eruptive style, and frequently display many different types, both passive and explosive, even in the span of a single eruptive cycle. [3] Volcanoes do not always erupt vertically from a single crater near their peak, either. Some volcanoes exhibit lateral and fissure eruptions.

  6. Volcanism - Wikipedia

    en.wikipedia.org/wiki/Volcanism

    Volcanism, vulcanism, volcanicity, or volcanic activity is the phenomenon where solids, liquids, gases, and their mixtures erupt to the surface of a solid-surface astronomical body such as a planet or a moon. [1]

  7. Volcano tectonics - Wikipedia

    en.wikipedia.org/wiki/Volcano_tectonics

    Volcano tectonics is a scientific field that uses the techniques and methods of structural geology, tectonics, and physics to analyse and interpret physical processes and the associated deformation in volcanic areas, at any scale.
