This resource describes the nature of pressure surfaces and explains the dynamic processes associated with the eruption model. It contains a movie depicting a cross-sectional view of an explosively erupting volcano, typical of a so-called Plinian eruption. Additionally, there is a link to a computer program, which allows the user to construct a diverse group of volcanic landforms through the simulation of variable types of eruptions. It can be downloaded free of charge.
