Hi Foreverwing, if I understand correctly, you want a reference for the fact that the Hidden World is a volcanic caldera, right? In the article above, the reference is the fourth one - Dean Deblois’ Reddit AMA. You have to scroll through a lot to find it when you visit the link, but Dean does specifically state it’s a volcanic caldera (or rather it’s the entrance). Hope this makes sense!
