Lava Fountain A jet of lava sprayed into the air by the rapid formation and expansion of gas bubbles in the molten rock is called a lava fountain. Lava fountains typically range from about 10 to 100 m in height, but occasionally reach more than 500 m. Fountaining may occur from isolated vents, along fissures, within active lava lakes, and from a lava tube when water gains access to the tube in a confined space.
