What are Lava Fountains?
A lava fountain is a violent eruption of molten material either from an active a vent, fissure or an active lava lake. Lava fountains can be found all over the world. The eruptions can vary from 5 meters in the air to 100 meters in the air, the have also been known the reach greater heights during more violent eruptions. Lava fountains are formed during the process of a gas bubble in the molten rock beneath the surface rapidly expending and forcing lava high into the atmosphere. These displays of nature can be a spectacular sight to watch. Although, you may not want to stand too close.
Lava fountains are not just native to Earth, as technology progresses more and more fountains are seen erupting in space. These eruptions are reaching great heights of 1.5km and hitting temperatures of 1600 Celsius.
During 1986, the Izu-Oshima volcano in Japan was the highest lava fountain to ever be recorded on Earth. The eruption started off close to the surface. This forced lava and other molten material out with a massive amount of force, causing the eruption to reach 1600 meters in the air.
However, the world’s longest continuous eruption took place during 1783, the volcano was called Laki Fissure in southern Iceland.
