Lava fountains are locations where lava (or magma if underground) gushes out of a subterranean chute in a continuous or sporadic fountain of molten rock. Lava fountains may feed into lava rivers or be contained within lava lakes. They may be found in regions with volcanic activity or fantasy lavalands. Lava fountains are much smaller than volcanoes. In game worlds these terrain features may act as terrain hazards.
