Map of Air routes and Volcanoes

Casadevall, Thomas, J., and Thompson, Theodore, B., 1995, World map of volcanoes and principal aeronautical features: U.S. Geological Survey Geophysical Investigations Series Map GP-1011, 1 plate.

This map shows the locations of the Earth's 1,330 volcanoes active in the last 10,000 years together with selected aeronautical navigation aids, and great-circle routes. The map was made is to inform people and increase awareness throughout the world about the close spatial relationship between volcanoes and aviation operations. The map can help all in the aviation industry and meteorologic and volcanic sciences to mitigate the threat that volcanic hazards pose to aircraft and thus help to improve aviation safety.

Report from 1991 International Symposium

Casadevall, Thomas, J. (ed.), 1994; Volcanic ash and aviation safety: proceedings of the First International Symposium on Volcanic Ash and Aviation Safety: U.S. Geological Survey Bulletin 2047, 450 p.

This report includes 60 brief (4-14 pages) technical reports about aviation and volcano ash issues and topics that were presented by scientists and aviation experts from around the world in Seattle, Washington, during a 1991 symposium. The aims of the symposium were to bring together individuals who were interested in the volcanic ash and aviation safety problem but who may have been unaware of other scientists, engineers, pilots, and aviation authorities with similar interests; to encourage and define needed improvements in the detection, tracking, and warning of volcanic ash hazard so that aircraft may avoid ash clouds; and to review the effects of volcanic ash on aircraft so that pilots who encounter ash can respond appropriately.

Pilot & Airline Training Video

Boeing Company; 1992, Volcanic ash avoidance -- flight crew briefing: Boeing Commercial Airplane Group, Customer Training and Flight Operations Support, 33 minutes.

What can pilots and airline dispatchers do to avoid volcanic eruption clouds, and if a pilot unexpectedly encounters an eruption cloud, what are the recommended steps the pilot should take? In addition to answering these questions, this training video shows how volcanic ash can affect jet aircraft and provides a gripping first-hand pilot's account of an incident in which a Boeing 747 encountered an eruption cloud and temporarily lost power in all four engines.
