Anatomy of a Volcano

  • 1980 ----- color ----- 57 min ----- vhs
  • (Nova series) The eruption of Mount St. Helens claimed scores of lives, turned lush forest into a vast wasteland and held a region in precarious danger for months. NOVA looks at the events leading up to the blast and analyzes the actual explosion, frame-by-frame, in a unique series of pictures. A helicopter carrying scientists and NOVA crew members travels through the poison gas plume, lands on ash of intense heat and visits survey posts set up in the mouth of the crater. Instruments yield valuable clues for scientists who look ahead to the next eruption with a better understanding of how to prevent a natural wonder from inflicting catastrophic damage.
