Images from the Tele13 Chaitén webcam, 27 February 2009. The left image was taken at 16:50 local time, the right image at 21:34 local time.

The Tele13 webcam (direct link here, link that opens in your default media player here) has been providing some of the most remarkable images of the Chaitén eruption that we have yet seen. The camera is located just south of Chaitén town and looks north. The images below were captured yesterday evening and overnight, and show partial collapses, debris flows and, in the images from after dark, the dome glowing and flickering with incandescence. There is a total of 19 images in this post: click on ‘more’ below to view the entire series.

The first sequence runs from 17:16 to 17:24 (all times are local) and shows a small collapse, ashen plumes and debris flows. Note the small debris flow descending the south flank of the dome in the image timed at 17:19.

1. Olivia - 28 February 2009: Increadible pictures!
Have the ashes crossed to Argentina?
2. Bruce S. - 1 March 2009: Funny too, how one’s own subjective perception changes due to the changing shape. This no longer looks like a dome but like a traditional stratovolcano.. as though we were watching a mountain grow before our eyes. Amazing how fast geology can actually be!!
