  2. Shield volcano - Wikipedia

    en.wikipedia.org/wiki/Shield_volcano

    A shield volcano is a type of volcano named for its low profile, resembling a shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano.

  3. List of shield volcanoes - Wikipedia

    en.wikipedia.org/wiki/List_of_shield_volcanoes

    This list of shield volcanoes includes active, dormant and extinct shield volcanoes. Shield volcanoes are one of the three types [ specify ] of volcanoes. They have a short cone shape, and have basaltic lava which means the lava has low viscosity (viscosity is a measure of the ability for a liquid to flow)

  4. Cascade Volcanoes - Wikipedia

    en.wikipedia.org/wiki/Cascade_Volcanoes

    The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21] However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, and therefore the great risk caused by volcanic activity in the regions is not always readily apparent.

  6. Explosive eruption - Wikipedia

    en.wikipedia.org/wiki/Explosive_eruption

    In volcanology, an explosive eruption is a volcanic eruption of the most violent type. A notable example is the 1980 eruption of Mount St. Helens. Such eruptions result when sufficient gas has dissolved under pressure within a viscous magma such that expelled lava violently froths into volcanic ash when pressure is suddenly lowered at the vent.

  7. Deccan Traps - Wikipedia

    en.wikipedia.org/wiki/Deccan_Traps

    The Deccan Traps are a large igneous province of west-central India (17–24°N, 73–74°E). They are one of the largest volcanic features on Earth, taking the form of a large shield volcano. [2] They consist of many layers of solidified flood basalt that together are more than about 2,000 metres (6,600 ft) thick, cover an area of about ...

    Mountain type. shield volcano. Skjaldbreiður (Icelandic pronunciation: [ˈscaltˌpreiːðʏr̥] ⓘ, "broad shield") is an Icelandic lava shield formed in a huge and quite protracted eruption series from about roughly 9,500 years ago. [ 2 ] The extensive lava fields which were produced by this eruption, flowed southwards, and formed the basin ...

    The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming. The caldera measures 43 by 28 miles (70 by 45 kilometers), and postcaldera ...
