Bibliography of literature from 1990-1997 pertaining to Holocene and fumarolic Pleistocene volcanoes of Alaska, Canada, and the conterminous United States
The 1980's and 1990's were marked by frequent worldwide destructive volcanic
eruptions. Significant loss of life and property during eruptions, and extensive media coverage of
volcanic events around the globe have brought volcanic processes and hazards increasingly to the
forefront of scientific, governmental, and public attention (e.g., Casadevall, 1994; Pringle, 1994).

Mobile Response Team Saves Lives in Volcano Crises
The world's only volcano crisis response team, organized and operated by the USGS, can be quickly mobilized to assess and monitor hazards at volcanoes threatening to erupt. Since 1986, the team has responded to more than a dozen volcano crises as part of the Volcano Disaster Assistance Program (VDAP), a cooperative effort with the Office of Foreign Disaster Assistance of the U.S. Agency for Intern

Volcanic hazards and aviation safety
An aeronautical chart was developed to determine the relative proximity of volcanoes or ash clouds to the airports and flight corridors that may be affected by volcanic debris. The map aims to inform and increase awareness about the close spatial relationship between volcanoes and aviation operations. It shows the locations of the active volcanoes together with selected aeronautical navigation aid
