AVO Image #41861

Satellite radar image from the TerraSAR-X sensor, showing the summit of Cleveland Volcano. Image collected on February 10, 2012, and shows the presence of a small lava dome within the summit crater. The summit crater is about 200 meters across. Note that satellite radar images have some inherent topographic distortion due to the manner in which they are collected.

AVO Image #41711

Annotated NOAA satellite image from 5:02 AM AST on 29 December 2011 showing a drifting ash cloud from a small eruption of Cleveland Volcano. The ash cloud is the yellow and orange feature located on the southwest tip of Umnak Island. The brief explosive eruption began at around 4:15 AM AST, and the cloud had drifted 35 miles to the east at an altitude of about 15,000 above sea level by the time is was observed in this satellite image. By 10:00 AM AST, the ash cloud had dispersed and was no longer visible in satellite data. Satellite data provided by UAFGI/GINA.

AVO Image #41601

Satellite radar image from the TerraSAR-X sensor of the summit of Cleveland Volcano collected on October 23, 2011 showing the summit crater and growth of the lava dome. The summit crater is about 200 meters across. Note that satellite radar images have some inherent topographic distortion due to the manner in which they are collected.

AVO Image #41542

Panchromatic satellite image of Cleveland Volcano collected by the Worldview-1 sensor on 7 October 2011. The summit of the volcano is mostly snow-covered, and the growing lava dome is seen as the dark feature in the center of the volcano (inset area outlined by black square). A faint steam and gas plume is observed moving towards the northeast (upper-right). The inset is a rotated close-up view showing the lava dome filling much of the summit crater. The inset also shows some snow-free areas just outside of the summit crater.

AVO Image #41502

Animation of satellite radar images from the TerraSAR-X sensor of the summit of Cleveland Volcano showing the summit crater and growth of the lava dome between August 7 and October 12, 2011. The summit crater is about 200 meters across. Note that satellite radar images have some inherent topographic distortion due to the manner in which they are collected.

AVO Image #41522

True-color satellite image of Cleveland Volcano collected by the Worldview-2 sensor on October 7, 2011. The summit of the volcano is mostly snow-covered, and the growing lava dome is seen as the dark feature in the center of the image. Some snow-free ground is observed on the southern upper flanks of the volcano, just south (below) the of the crater. A faint steam and gas plume is observed moving towards the northeast (upper-right).
