GEOLOGY

Detailed explanation-1: -Dormant volcanoes have not erupted for a very long time but may erupt at a future time.

Detailed explanation-2: -Volcanologists use that term as shorthand for “potentially active, ” so a “dormant” volcano is one that is not erupting now, but that is considered “active” because it could erupt in the future. Mount Hood is an active volcano that is currently dormant. Kīlauea is an active volcano that is currently erupting.

Detailed explanation-3: -Dormant → Dormant volcanoes are volcanoes that have not erupted in a long time but are expected to erupt again in the future. Examples of dormant volcanoes are Mount Kilimanjaro, Tanzania, Africa and Mount Fuji in Japan.

Detailed explanation-4: -Volcanoes go dormant because magma from the Earth’s mantle can no longer reach the volcano. For example, in Hawaii, the line of islands are slowly moving to the northwest. Meanwhile, the supply of magma stays in the same place within the Earth, which currently happens to lie beneath the Big Island.

Detailed explanation-5: -Inactive volcanoes are also called dormant or sleeping volcanoes. These volcanoes are expected to erupt again at some point, despite being dormant for thousands of years. Examples of inactive volcanoes are Mount Fuji and Mount Rainier.
