ASH FALL AND ASH CLOUD FORECASTS: MODEL OUTPUT
Mathematical models help forecast where an ash cloud will drift, how fast, and how high, as well as where ash will reach the ground. These products from USGS, NOAA, and UAF use forecast winds and assumptions about the size of the eruption to generate forecast graphics. AVO runs these models when a volcano is restless to know where ash would go IF an eruption occurred. This DOES NOT mean that an ash cloud has been produced. For actual eruptions, AVO will update models with better information as it becomes available. Click on individual models graphics to learn more.
