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.

Caption:AVHRR satellite data from February 7, 2014, 1704 UTC show a drifting ice-rich cloud south of Shishaldin. Comparison of temperature data and trajectory suggest a height of 20,000 to 25,000 ft. Mid-IR data from after this event show no evidence of hot material on the flanks, suggesting that this was a gas-rich exhalation event.

Caption:Satellite image of Unimak Island showing elevated surface temperatures in the summit crater of Shishaldin Volcano. This mid-infrared image is scaled so that warm values are bright white and cold values (like high clouds are dark). The elevated surface temperatures are visible as the white pixels within the yellow circle that indicates the location of Shishaldin.
