This picture shows a lava fountain taken of the Pu`u `O`o cinder and spatter
cone on the Kilauea Volcano, Hawaii. It was photographed by J.D. Griggs on
October 5, 1983.
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.
