Which volcano classification describes a volcano that erupts constantly?

The classification of a volcano that erupts constantly is described as active. An active volcano is one that has erupted recently and shows signs of erupting again in the near future. This term indicates ongoing volcanic activity, as opposed to dormant or extinct volcanoes. Dormant volcanoes are those that have not erupted in a long time but could potentially erupt again, while extinct volcanoes are unlikely to erupt again. The term intermittent can refer to volcanoes that erupt occasionally but not in a constant manner, distinguishing them from those classified as active. Thus, active is the most appropriate classification for a volcano with continuous eruptions.
