A lava fountain is a volcanic phenomenon in which lava is forcefully but non-explosively ejected from a crater, vent, or fissure. Lava fountains may reach heights of up to 500 m (1,640 ft). They may occur as a series of short pulses, or a continuous jet of lava. They are commonly seen in Hawaiian eruptions.
