Fissure 8 lava fountains

Fissure 8 lava fountains ...

Detailed Description

What a difference four days makes. This thermal image of Fissure 8 fountains from the Lower East Rift Zone eruption of Kīlauea shows a few things. 1) The two lava fountains have gained height - tallest one from 150 ft to over 250 ft. 2) A Pu‘u has built up downwind. 3) The amount of material wafting downwind is greater. Scientifically, we know the fountain temperatures are reaching up to about 2040 degrees F (1115 C). The composition of the lava erupted has high MgO (magnesium oxide) values, which comes from olivine crystals that are being pulled from deep in the rift zone.
