Site of the Day for Wednesday, October 6, 2004 How Volcanoes Work Today's site is a comprehensive scientific presentation on volcanoes by Dr. V. Camp of San Diego University's Department of Geological Sciences. Gentle Subscribers will discover an excellent exposition on volcano dynamics, accompanied by spectacular photos and illuminating diagrams. "This website is an educational resource that describes the science behind volcanoes and volcanic processes. Each section in the menu builds upon previous sections. For users who lack fundamental knowledge of volcanological principles and terms, it is best to proceed through the website in a progressive manner. More advanced users will find each section self-contained and can navigate through the website as their interest dictates." - from the website The site covers the broad categories of eruption, landforms, the substances produced by eruptions, eruption types and historical eruptions. These are further broken down into subjects such as the volcano-tectonic environments, with diagrams of the distribution of active volcanoes around the world and plate motion, mantle convection, and magma generation. The landforms section offers information on how volcanoes are classified according to their eruption patterns and general shapes. In the historical eruptions module, some of the more dramatic volcanic eruptions, such as Mt. St. Helens in 1980, are featured.
