The volcano is said to be extinct if it hasn't erupted for at least 10,000 years.
An extinct volcano is one that will never erupt again.
As it is regarded as an extinct volcano, it is unlikely that it will erupt again.
They term this an extinct volcano if there is no longer a supply of magma to the chamber underlying the volcano or dormant if there is (as there is therefore still a chance of a future eruption).
If it 'unlikely' to erupt again but it could, it's dormant.
A dormant volcano is one that is just sleeping and it is possible to erupt again. An extinct volcano will never erupt again.
