USGS Ashfall Report

The Alaska Volcano Observatory (AVO) is a joint program of the United States Geological Survey (USGS), the Geophysical Institute of the University of Alaska Fairbanks (UAFGI), and the State of Alaska Division of Geological and Geophysical Surveys (ADGGS). AVO was formed in 1988, and uses federal, state, and university resources to monitor and study Alaska's hazardous volcanoes, to predict and record eruptive activity, and to mitigate volcanic hazards to life and property. This project creates a database module and web interface allowing the public and Alaska Volcano Observatory (AVO) staff to enter reports of ash fall in their local area in real time and retrospectively following an eruptive event. Users browsing the AVO web site during eruptions are directed towards a web form allowing them to fill in ash fall information and submit the information to AVO.
