Fissure 8 lava fountains

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.
