Observatories and Official Agencies

• Volcanoes of Canada
• This Geological Survey of Canada site is a resource to learn more about Canadian volcanoes and volcanology. Users can get introductory information, learn about types of volcanoes and eruptions, their hazards, how they are monitored, and how to become a volcanologist. Explore a database of more than 200 Canadian volcanic features via a Volcano Map or the Catalogue of Canadian Volcanoes.
• Cascades Volcano Observatory
• This observatory maintained by the Volcano Hazards Program of the U.S. Geological Survey strives to serve the national interest by helping people to live knowledgeably and safely with volcanoes and related natural hazards including earthquakes, landslides, and debris flows in the western United States and elsewhere in the world. Special features include News and Current Events, Cascade Range Current Activity Updates, Cascade Range Volcanoes Summary, Hazards Assessment Reports and Maps, Educational Outreach, Living With Volcanoes, and Visit a Volcano. Lots of excellent sections, such as the photo archive and glossary of hazards, features, and terminology. Also information about the Volcanic Disaster Assistance Program.
• Long Valley Observatory
• Information provided by the Volcano Hazards Program of the U.S. Geological Survey. Location and background, current unrest, monitoring data (seismicity, deformation, and gases & hot-spring chemistry), response plan, "Observatory" organization, and geologic history.
• Yellowstone Volcano Observatory
• This observatory maintained by the Volcano Hazards Program of the U.S. Geological Survey, Yellowstone National Park, and the University of Utah, is a long-term, instrument-based monitoring facility designed for observing volcanic and earthquake activity in the Yellowstone National Park region.

Additional Information

• Volcano World: North America
• Images, basic information, and references. Not restricted to Holocene volcanoes. Includes Mexico, Alaska, Hawaii, and the West Indies.
• U.S. Geological Survey, Flagstaff Field Center: Volcanoes and Geothermal Energy
• Overview of the volcanological work being done by the USGS in Arizona's San Francisco Volcanic Field.
• Canadian Meteorological Center: VAAC Montréal
• This Volcanic Ash Advisory Centre (VAAC) has an area of responsibility covering the airspace of Canada, its adjacent waters, and the northwest Atlantic. The Canadian Emergency Response Model (CANERM) is designed to produce quick and real-time ash dispersion simulations in a forecast or diagnostic mode. Graphical results are available for past eruptions and for selected volcanoes that could potentially affect the area. Good introduction to the subject from a paper presented at the "Pan Pacific Hazards '96" conference.
• Volcanic Ash Advisory Statements
• Aviation notices issued by the Montreal Volcanic Ash Advisory Center (VAAC). Coverage area includes Canada, Greenland and adjacent Arctic waters, and the North Atlantic.
• Volcanic Ash Advisory Statements
• Aviation notices issued by the Washington Volcanic Ash Advisory Center (VAAC). Coverage area includes the continental United States.

Volcano Sites

• The Official Home Page of Yellowstone National Park
• This National Park Service website has information about all aspects of the park, especially the thermal areas.
• Yellowstone Research Projects
• Bob Smith, a professor at the University of Utah, has research interests that include the geodynamics and evolution of the Yellowstone hotspot and caldera, seismicity and volcanic hazards of Yellowstone, and operation of the Yellowstone seismograph network. Subpages about these topics contain extensive information.
• Yellowstone's Geysers
• Yellowstone National Park is home to some 10,000 thermal features, over 500 hundred of which are geysers. In fact, Yellowstone contains the majority of the worlds geysers. The four basic types of thermal features present in the Park are geysers, hot springs, fumaroles, and mudpots. Many of these are concentrated in Yellowstone's major geyser basins: Upper, Midway, Lower, Norris, West Thumb, Shoshone and Heart Lake.
