GEOLOGY

Detailed explanation-1: -Active volcanoes have a recent history of eruptions; they are likely to erupt again. Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects.

Detailed explanation-2: -Mauna Loa Erupts The largest active volcano in the world, Mauna Loa, erupted for about 12 days in late 2022, the first eruption since 1984.

Detailed explanation-3: -Mauna Loa erupted most recently in 1984, and will erupt again in the future, posing significant risks to people living on the flanks of the volcano.

Detailed explanation-4: -The six eruption types are in order from least explosive to the most explosive; Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian. Notice how, as the eruptions become more violent, the cone shapes become more steeply constructed. You will read about these volcanic types in more depth later in the lesson.
