The highest lava fountain ever recorded occurred in 1986 on the Izu-Oshima volcano in Japan. It reached a height of 1,600 meters (5,200 ft.). The world's longest continuous lava fountain in historical time was erupted from the 25-km long Laki Fissure in southern Iceland in 1783.
Lava fountains have also been observed beyond Earth, in the Tvashtar region of Jupiter's volcanically active moon Io. The Tvashtar fountains have been seen to reach a height of more than 1.5 km and involve lava at a temperature of 1,000 K to 1,600 K.
