In a field test of their instrument, University at Buffalo researchers gathered viscosity data from lava flows at the Litli-Hrútur eruption in Iceland. Disclaimer: AAAS and EurekAlert!

Hawaii’s Kilauea volcano has erupted again, sending lava fountains soaring up to 1,000 feet in a breathtaking display.

It can hold hundreds of kilos of lava and execute experiments about viscosity, morphology, structures, and formations. But she's a little bit finicky when it comes to lava-making. Bob: The furnace ...

called alkaline lava, has an extremely low viscosity, making it almost as fluid as water. Alkaline lava has a melting temperature in excess of 2,000 degrees Fahrenheit. The fluidity and extreme ...

A lava tube may also form, beneath the surface of the ground, when low viscosity lava develops a hard crust through which lava flows.
