Kasatochi sunsets

The eruption of Kasatochi volcano in the Aleutian Islands on 7 August injected a very large amount of ash and gas into the atmosphere, including reportedly the largest stratospheric sulphur dioxide cloud since the eruption of Cerro Hudson in 1991. Kasatochi’s aerosols are now producing dramatic and beautiful sunsets across the northern hemisphere.

SpaceWeather.com has a collection of images from locations in the United States and Europe; LiveScience has a good article with some pictures; and there are many Kasatochi sky images at Flickr.

UPDATE: Dave Schumaker has a new post on Kasatochi today (6 September) at Geology News which includes many wonderful images of the recent volcanic sunsets: Kasatochi Eruption and Sunsets.
