    VOLCANO VIDEOS
    USGS Cascades Volcano Observatory has produced a video, Perilous Beauty, about the risk of lahars from Mount Rainier. Another video, Reducing Volcanic Risk, about the risks posed by volcanos, has been produced by the International Association of Volcanology and Chemisty of the Earth's Interior (IAVCEI) and the United Nations Educational Scientific and Cultural Organization (UNESCO). A short description of each video is given below.

    You can order these videos by mail with an enclosed check made out to NWIA or by phone or fax with VISA credit card from:

    Perilous Beauty: The Hidden Dangers of Mount Rainier
    Volcanic activity, enormous landslides, and glacial erosion have continuously re-shaped Mount Rainier's magnificent cone. These natural processes have also sent large and dangerous mudflows rushing down all river valleys leading away from the volcano.

    Understanding the nature of these past events is key to reducing our risk from Mount Rainier's future activity. This 29-minute video uses computer animation, eruption footage, interviews with scientists, and vivid aerial and ground shots of the mountain to show how mudflows from Mount Rainier can affect communities in Western Washington.


    Reducing Volcanic Risk

    This videotape showcases how people can lower their risk from volcanic activity. Three steps can volcanic eruptions from becoming volcanic disasters:


    Stunning video of volcanos from around the world shows how these three steps saved lives when they were used. Reducing Volcanic Risk also describes the critical elements of emergency plans that made the difference between life and death for tens of thousands of people living in the shadows of active volcanos. People must be informed of the volcano hazards they face. Scientists and public officials must announce warnings clearly. And emergency plans must be tested and practiced ahead of time and used without hesitation when a volcano threatens to erupt.

    This 20-minute eductional program and its companion, Understanding Volcanic Hazards, are intended to help prevent future deaths from volcanic eruptions.
