IMAGE 58231
AVO Image

This great weather we've been having has given us some super satellite looks at Shishaldin Volcano on Unimak Islands in the normally cloudy Aleutians. In this side by side pair of May 15, 2014 NASA Aqua satellite images (http://aqua.nasa.gov/; true color on the left, mid-infrared brightness on the right), you can see the still snow-covered volcanoes of Unimak, pointy Shishaldin in the middle of the island. On the right, the red circle encloses a few bright pixels that indicate significant heat down inside the Shishaldin summit crater. We interpret this to be good evidence of low-level eruptive activity involving lava. As of yet, we've only seen photographs of a small amount of ash and debris on the crater rim and upper slopes of Shishaldin.
