Nearly three years after Kilauea Volcano started spewing lava within the Leilani Estates subdivision in Lower Puna, the historic eruption of 2018 continues to fuel scientific study.

“But magma viscosity is usually only quantified well after an eruption, not in advance,” explained Diana Roman, lead author of the study and volcanologist at Carnegie institution for Science.

The Jeffreys Equation assumes a crystal free magma, but if significant crystallization has occurred, then the viscosity will increase as well. As you add solids to the melt, the viscosity will ...

April 7 (UPI) --Scientists were able to estimate the viscosity of magma inside Hawaii's Kilauea Volcano by studying fault movements before and during the volcano's eruption in 2018. The ...

The properties of the magma inside a volcano affect how an eruption will play out. In particular, the viscosity of this molten rock is a major factor in influencing how hazardous an eruption could ...

X-rays suggest lower-mantle magma could be stabilized by heavy elements “Nanoparticles suspended in a very low viscosity fluid appear to have a great effect increasing the bulk viscosity of the ...

When the magma is runny, like at Kīlauea, the fountains might go from a thousand feet tall to a few tens of feet as the viscosity gets higher, usually due to cooling.

The properties of the magma inside a volcano affect how an eruption will play out. In particular, the viscosity of this molten rock is a major factor in influencing how hazardous an eruption could ...

The obvious one is magma viscosity – how sticky it is – and that is normally a function of how much silica is in the magma and how hot it is. Less silica and hotter temperatures mean a runnier magma.
