Kasatochi Satellite Imagery



For the latest updates on this volcano, please visit the Alaska Volcano Observatory.

Narrative courtesy of the Alaska Volcano Observatory


Three major explosive eruptions occurred at Kasatochi between approximately 2230 UTC (2:30 PM AKDT) on 07 August and 0500 UTC on 08 August (9:00PM AKDT on 07 August). Ash from these explosions reached at least 45,000 ft above sea level. Ash emissions became continuous following the last explosive event and have produced a continuous ash cloud extending for more than 500 miles in counterclockwise spiral.



This is an infrared satellite image from the Defense Meteorological Satellite Program (DMSP) polar orbiting satellite. An infrared satellite measures the temperature of the top of a cloud, with the dark red and purples signifying the coldest tops.




Imagery was visually enhanced to highlight cloud contrast during high and low light

This is a visible satellite image of the eruption. A visible satellite image depicts what would actually be seen if viewed from space. Note the two distinct eruptions and the large continuous emission of ash.
