Full Answer

The U.S. Geological Survey has classified 18 volcanoes in the country to be extremely-high-threat volcanoes, five of which are found in Alaska. These include Akutan Volcano, Augustine Volcano, Makushin Volcano, Redoubt Volcano and Spurr Volcano. Most of Alaska's volcanoes are situated along the Aleutian Arc, which extends for 1,550 miles. Experts believe that eruptions originating from the Cook Inlet volcanoes, comprised of Augustine, Redoubt, Spurr and Iliamna, may result to severe damages and heavy casualties, as these volcanoes are closest to Anchorage, the state's most populous city.

  • Q:

    How do volcanoes erupt?

    A:

    Volcanic eruptions can either be effusive or explosive. An effusive volcanic eruption occurs when the lava pours out onto the ground from the volcano's vent. When the molten rock or magma is thin and runny, gases can easily escape and the lava flows freely and travels far. An explosive volcanic eruption is caused by thick and sticky magma, which prevents gases from escaping and causes them to explode violently.
