Dynamics of Eruption Cloud
During explosive volcanic eruptions, a mixture of volcanic gas and solid particle (volcanic ash, lapilli and bomb) is ejected from the volcanic vent into atmospehre. Such a eruption generates eruption columns and pyroclastic flows. I am investigating the dynamics of eruption clouds using numerical simulations.
