A lava fountain is a large amount of lava that is thrown up into the air when gas bubbles expand in the melted rock. Most lava fountains range in height from 30 to 300 feet. Sometimes the fountain can be as tall as 1,500 feet tall.
Lava fountains erupt inside lava lakes, along a fissure, isolated vents or from lava tubes.
