maybe it can be both? If it is a polygon it would describe the vent, while a node would mark the highest point?

There could maybe also be vulcanoes that are now a depression rather than a peak (e.g. the thing collapsed)?

There are also 708 https://taginfo.openstreetmap.org/tags/geological=volcanic_vent

and 131 natural=volcanic_vent

I would prefer these tags for explicit vents, as they remove the ambiguity.
