Sulfur, Magma, and the Velocity of Bubbles in Volcanic Eruptions

Gaseous flow of sulfur in a crystal-poor magma under the surface is an interesting study in the field of volcanism. Scientists are using computer simulations and mathematical constructs to test why some volcanoes erupt more violently and gaseously than others.

Why are volcanologists interested in vapour bubbles? Because they can accumulate in a magma reservoir underneath a volcano, priming it to explode. Researchers at ETH Zurich and Georgia Institute of Technology have now discovered how bubbles are able to accumulate in the magma.
