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 be for nearby communities. But it usually only quantified well after an eruption. New work identifies an indicator of magma viscosity that can be measured before an eruption. This could help scientists and emergency managers understand possible patterns of future eruptions.
