Impacts of Volcanic Gases on Climate, the Environment, and People

U.S. Geological Survey Open-File Report 97-262
Version 1.0

By Kenneth A. McGee, Michael P. Doukas, Richard Kessler, and Terrence M. Gerlach


Gases from volcanoes give rise to numerous impacts on climate, the environment, and people. U.S. Geological Survey (USGS) scientists are inventorying gas emissions at many of the almost 70 active volcanoes in the United States. This effort helps build a better understanding of the dynamic processes at work on the Earth's surface and is contributing important new information on how volcanic emissions affect global change.
