That tag is practically non-verifiable and therefore does not really 
belong in OSM.  But since everyone is free to add any tags they want in 
OSM such tags of course exist.

Reason for the lack of verifiability is that what an active volcano is 
in almost all uses of this term does not depend on the current state of 
the volcano but on its history - most commonly during the holocene (10k 
years) or during historic times.
