Toasting Marshmallows

I was wondering what a gang of volcanoes would do if they were at a party together and decided they would toast marshmallows. I guess those are NOT wooden stakes they are using or else they’d burn them up.
I wonder what the collective for a gang of volcanoes would be.

An eruption of volcanoes?

A tectonic event of volcanoes?
