The authors simulate bubble nucleation in silica-rich magma with conditions appropriate for Plinian eruptions. They demonstrate that the gap between decompression rate estimates from bubble number density and independent geospeedometers can be largely closed if nucleation is heterogenous facilitated by magnetite crystals and decompression rate is calculated as time-averaged values.
