Note:
The reawakening of Mount St. Helens volcano in March 1980, and its catastrophic eruption of May 18, surely will rank among the most significant geologic events in the United States in the 20th century. The debris avalanche, explosive eruption, and associated mudflows and floods resulted in the loss of about 60 lives-including our own David Johnston-and property damage and destruction totaling billions of dollars. We in the U.S. Geological Survey are proud of the role we played in helping to minimize these losses. By its Organic Act of 1879, the Geological Survey was charged with "classification of the public lands, and examination of the geological structure, mineral resources, and products of the nationai domain* * *." Under that charge, volcanoes and volcanic processesancient and contemporary-have been studied to advance the knowledge of the geology in our country. Within the last several decades, attention has been directed increasingly toward assessment of the risks to life and property posed by geologic hazards, including volcanic eruptions, earthquakes, and ground failures.
