Cascades Volcano Observatory

Provided by the U.S. Geological Survey this site offers a good starting point to learn about volcanoes. One of the most useful features is the CVO-WEB Index. Using the index, students can quickly find most of the active volcanoes in the world, specific terms or features of volcanoes, and links to take them there. There are also links to abstracts of articles and reports. Excellent photos of volcanoes are available and some real-time shots of selected volcanoes around the world.
