Good idea.  So I did some digging.  There are no scientifically-agreed
definitions of the terms.  It's more of a folksonomy that scientists
use when talking to "folks."  See
(it's fairly representative of other definitions I've found).  It's messy.
There's a
"it hasn't erupted in X years so it's dormant" definition in there, but
like Yellowstone are excluded.  Iceland's volcanoes are very
interconnected.  Etc.

About the only characteristic I've seen so far upon which there is broad
agreement (and is verifiable by ordinary mappers) is the presence of a lava
lake (which many people probably think of when they see the term "active
volcano").  That's mappable, in my opinion.

If we can pin any other terms down more precisely, and show that scientists
with those definitions, and scientific literature that meets a general
consensus is available classifying volcanoes in those terms, then I'm all
for it.
