Understanding the plume dynamics of explosive super-eruptions

Super-eruptions such as Toba generate large co-ignimbrite plumes, but their behaviour is not fully understood. Here, the authors show that super-eruption plumes behave differently to Plinian eruptions and can generate over-plumes into the mesosphere, which would amplify their impact on the climate.
