Caption:AVHRR satellite image showing elevated surface temperatures at Pavlof (white pixels are hot; the black pixel is a recovery pixel) suggesting lava at the surface. The faint white line headed northeast from the volcano is a low-level steam plume also visible in the FAA web camera located in Cold Bay. A pilot reported a gas and ash plume drifting north at 7,000 to 8,000 feet above sea level. This image was taken at 8:40 am on May 31, 2014.

Caption: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.

Caption:Aerial view of Shishaldin Volcano on May 14, 2015. Note the gray discoloration of the upper flank snow and ice cover. This material is most likely ash produced by low-level eruptive activity within the summit crater.

Caption:These are examples of small explosions in Shishaldin's crater that have been recorded at station SSBA. Each explosion shows up as a low-frequency seismic wave that travels through the ground, followed by a high-frequency airwave pulse. The airwaves arrive later because energy from the explosion travels more slowly through the air than it does through the ground.

Caption:Animated sequence of satellite images of small ash clouds from Cleveland (small black circle), February 25, 2014. Infrasound and lightning alarms detected two small explosions at Cleveland Volcano at ~4:17 UTC February 25 (19:17 AKST February 24) and 10:35 UTC (1:35 AKST) February 25. The earliest image in this gif is from 6:45 AM UTC, the middle image is from 1:47 PM UTC, and the last image in the sequence is from 3:15 PM UTC. The ash is circled in red, estimated altitude of 16,000 ft asl. These explosions are typical of eruptive activity of Cleveland over the past few years. There may be a heightened chance of additional ash emissions in the coming weeks. Because these explosions were brief and there is no sign of ongoing eruption, Cleveland remains at Volcano Alert Level/Aviation Color Code YELLOW/ADVISORY.
