Volcanic Plume - John Seach

A volcanic plume is a mixture of particles and gas emitted by an eruption.
Plumes may reach heights of 80 km in large eruptions.
The plume is generated by fragmentation of magma.

The plume has 3 phases.
Jet Phase is dominated by upward momentum.
Convective Phase is where the  plume rises by buoyant convection.
Umbrella Phase is where the plume spreads out.
