Magma fragmentation and volcanic eruption style
Some volcanoes release lava slowly while others throw ash into the stratosphere, and many restless volcanoes never erupt. The physics deciding these outcomes happens deep underground where it cannot be watched directly.
Why it matters
Forecasting whether and how a volcano will erupt is the basis of hazard warnings for hundreds of millions of people.
