They're all different. Some erupt multiple times a day, some are dead (never erupt)

About every 20 years
Denmark has no vulcanos.
There's 130 active volcanoes and 76 volcanoes have erupted in historic time.
It is called a active volcano. Inactive volcanoes have not erupted for more than a century.
Most of the volcanoes in the world, including composite volcanoes, are considered active. Scientists consider any volcano that has erupted in the last 10,000 years active.
Mt. St. Helens erupted in 1980 and is still active as a hot ash volcano.
Denmark has no vulcanos.
Active volcanoes and dormant volcanoes both have a likely chance to erupt and have erupted in the past.
There's 130 active volcanoes and 76 volcanoes have erupted in historic time.
If it has erupted in the past 12,000 years

Active volcanoes: are those that erupted lava,gases ,cinder,pumice,etc in the historic pass.Eg: Mt.St.Helena Dormant volcanoes: are those which erupted in the past and are likely to erupt again after remeaining inactive for fairly long periods. These are "sleeping" volcanoes which may become active once again. eg: Mt.vesuvius.Extinct volcanoes: are those volcanoes which were active in the remote geological periods. Eg: Mt.Kenya
Active volcanoes are likely to erupt at any time where as inactive volcanoes are 'asleep' or haven't erupted much in the past and are unlikely to erupt in the near future.
There are about 168 volcanoes in Indonesia. Only 23 49 or 76 are active, . this may not be the only answer you find but I believe this answer.
An active volcano is one that is currently in a state of regular eruptions; it likely would have erupted in the last few decades. A dormant volcano is one that is capable of erupting but hasn't erupted in a long time.
Active: is erupting or has erupted recently Dormant: has not erupted recently but may erupt in the future. Could be considered "sleeping". Extinct: Will never erupt again
Mt. St. Helens erupted in 1980 and is still active as a hot ash volcano.
