Volcano is a geological term that refers to a mountain or hill formed by the accumulation of lava, ash, and other volcanic materials erupted from a vent in the Earth's crust.
Therefore, a volcano is always a volcano, regardless of whether it is currently erupting or not.
Active volcanoes are those that have erupted in the recent past and are likely to erupt again.
Dormant volcanoes are those that are not currently erupting but have the potential to erupt in the future.
Extinct volcanoes are those that are no longer expected to erupt.
So, while an erupting volcano might be considered "active," a volcano is always a volcano, even when it's quiet.
