GEOLOGY

Detailed explanation-1: -Extinct → Extinct volcanoes are those which have not erupted in human history.

Detailed explanation-2: -An extinct volcano is “dead”-it hasn’t erupted in the past 10, 000 years and is not expected to ever erupt again. Kohala on the Big Island of Hawaii could be considered an extinct volcano.

Detailed explanation-3: -Extinct volcanoes are the ones which have not been active from tens of thousands of years. So they are considered dead and are not expected to erupt in future whereas dormant volcanoes are the ones which have not erupted from a long time but are expected to erupt in the future.

Detailed explanation-4: -Extinct Volcano is a volcano that hasn’t erupted in 10, 000 years. The lava supply of the extinct volcano has run out. An extinct volcano is no longer located near a geologic hotspot that is active. It might be difficult to verify whether a volcano is genuinely extinct.

Detailed explanation-5: -As such, some volcanologists refer to extinct volcanoes as inactive, and some volcanoes once thought to be extinct are now referred to as dormant.
