Volcanic Hollow



The Underground Volcano is an area first introduced in Monster Hunter 4. It consists of an active volcano and the surrounding area is the Underground Cave after the dormant volcano becomes active and erupts. The main feature that sets the 4th Generation Volcano apart from the others is that most of the area is primarily underground. The "Mole Tribe" people apparently visit the Underground Volcano quite often, as such, they have vast knowledge of the area and its hazards.
