Volcanic Ash Alert System

The Alaska Volcano Observatory at UAF analyzes satellite data twice daily for thermal anomalies and ash plumes for about 80 volcanoes in the North Pacific. Thermal anomalies at volcanic vents have been detected up to several weeks before large eruptions. Volcanic ash in the atmosphere is a serious hazard to jet aircraft; working with the National Weather Service to predict where winds will carry the ash, UA assists the Federal Aviation Administration in warning pilots of potential risks.
