IMAGE 11086
AVO Image

Image from the King Salmon NEXRAD weather radar showing the volcanic cloud at Fourpeaked Mountain volcano on September 17, 2006 at 12:40 ADT (20:40 UTC). The color scheme shows a scale of radar reflectivity from light blue (low) to dark green (moderate), which corresponds to greater numbers and/or sizes of particles in the atmoshphere. It cannot be determined from this data alone whether the radar signal is due to large water droplets, ice particles, coarse-grained volcanic ash, or a mixture of these.
