Do volcanoes erupt regularly?
Volcanoes might also be active, intermittent, dormant or extinct depending on how often they erupt. Active volcanoes erupt often. Intermittent volcanoes erupt at regular intervals. Dormant volcanoes have been inactive for a long time. They are the most dangerous due to the fact they are only ‘sleeping’ and can erupt barring warning. Extinct volcanoes have now not erupted for lots of years. It is tough to distinguish between dormant and extinct volcanoes because some volcanoes can also stay quiet for a long time before all at once turning into lively again.
