A volcano is extinct if it remains dormant for 10,000 years. A volcano might become extinct when the eruption is so violent and explosive that the whole structure of the volcano is blown away. Another reason is the hotspot theory. A hotspot is located in the middle of a plate (below it). When the hotspot emits magma, it will form a volcano. As the plate moves, the volcano located on the plate moves together with it. It is then cut off from the magma source which is the hotspot, and it becomes extinct. The process will then repeat itself.

∙ 15y agoIf the volcano has not erupted in recorded history then scientists can say that it is not dormant, but extinct.

∙ 14y agoscientists record how long it doesnt explode and if it doesnt explode for a long time it is extinct. although no one will know for sure

You can also look inside it and if you melt then its also active.

Is a composite volcano active or domant?
A composite volcano may be active, dormant or extinct. The type of volcano does not determine its activity level.
What is an extinct volcano called?
An extinct volcano is one that scientists believe will not erupt again. That is because the volcano no longer has a magma supply. There are many volcanoes that are considered extinct on the Hawaiian islands. Exactly when a volcano has become extinct can be difficult, if not impossible, for scientists to determine.
Are cinder cone volcanoes dormant?
The type of volcano does not determine its level of acitivty. A cinder cone volcano may be active, dormant, or extinct.
What do geologists call a volcano if it never erupts again?
extinct volcano

extinct volcano
What is the difference between an extinct and a dormant earthquake?
An earthquake is a result of movement along a fault line, so they aren't classified as extinct and dormant. If you mean volcanoes, an extinct volcano is one that scientists classify as unlikely to erupt again because it no longer has lava supply. A dormant volcano is one scientists believe can still be active but has not had an eruption in recent years.
Is mount villarica extinct?
Volcano Villarica is not extinct it is an active volcano.
When is a volcano said to be extinct?
A volcano is said to be extinct when it isn't there any more.
Is Bennachie an extinct volcano?
Bennachie, a mountain in Aberdeenshire, Scotland is an extinct volcano.
How does an active volcano differ from a extinct volcano?
A dormant volcano is one that is just sleeping and it is possible to erupt again. An extinct volcano will never erupt again.
How is an extinct volcano formed?
if a rift zone stops speeding, the volcano will become extinct:)
