VESUVIUS 2000 is an interdisciplinary project aimed at producing a safe and prosperous habitat for the people living around Vesuvius. To produce this environment requires an effective collaboration between the experts and the public, whereby the danger from the volcano is used to reorganize the territory and thus produce new opportunities for the people surrounding the volcano. As an all inclusive physico-mathematical-computer model of the volcano, the Global Volcanic Simulator is a key tool for determining the effects of different eruption scenarios and thus for urban planning of the...

In this volume the author gives a detailed presentation of his theory of multiphase mixtures with structure. The book also addresses students, and in addition encourages further research. Based on the concept of averaging the field equations, conservation and balance equations are developed. A material deformation postulate leads to structured mixtures. The resulting model is compared with those in use elsewhere. The final chapters are devoted to constitutive theory and constitutive equations. In particular, two-phase mixtures are treated in some detail.

The topics incorporated in this volume include: foundations of transport theory; properties of igneous materials; mantle convection and melt segregation; magma chambers; magma ascent in conduits; and pyroclastic dispersions.

Volcanic eruptions are fascinating manifestations of the Earth's dynamic inte- rior which has been cooling for the past several billion years. The planets of the solar system originated some 4.5 billion years ago from the same gas and dust cloud created by the big bang. Some of the gas collapsed by the gravitational force to form the Sun at the center, while the whirling disk of gas and dust around the Sun subsequently cooled and lumped together to form larger and larger lumps of materials or planetesimals. These planetesimals collided fre- quently and violently and in the process liberated...
