A new instrument for measuring lava viscosity could revolutionize how scientists predict and respond to volcanic eruptions by providing more accurate data from the field.

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

“When lava erupts from a volcano, a lot of different gases are trapped as bubbles within the lava,” said Harris. “When we do measurements in the lab, we cannot put the gas back in. So, what we measure is a representation of the lava without all the different components, and we miss something that influences how the lava can flow.”The only solution is to take measurements in the field. This, however, comes with its own set of challenges.
“We spent almost two weeks accessing different locations around the Litli-Hrútur eruption,” said Harris. “It was a lot of very long hours in a pretty intense environment, but I think in the end, we were all really impressed and satisfied with the work that we were able to do.”
