No, the tag does not have a consistent meaning, it simply means some 
mapper has at some point subjectively considered this feature to be an 
active volcano.

OSM in general does not map historic features or events.  You should map 
what is at present verifiable to observe.  If there are fumarolic 
activites, hot springs etc. you can map these using appropriate tags 
(geological=volcanic_fumarole, natural=hot_spring etc.).
