Definition: Vomiting fire.
The word ignivomous stems from two Latin words- ignis (fire) and vomere (to vomit). It originates sometime around 1600.
Why this word?
While the word volcano may refer to the same exact thing, I happen to like the imagery conveyed with this word. It is the more poetic and dramatic verbal sibling of volcano. The volcano is indeed vomiting fire if you can conceive of its uppermost opening as being its mouth, spewing its contents into our atmosphere. I believe the only downside is that this word does not appropriately convey the danger involved with a volcanic eruption, instead downgrading it more to the environmental equivalent of the aftermath of a frat party. Personally I don’t like to think of a potentially dangerous volcano as either hung over or with a stomach bug, but the image brought to mind is certainly vivid.
