Clockwise from upper left is a Voyager 1 high resolution image, a Voyager 1 color image, a Galileo color image, and a Voyager 2 color image.
North is to the top of the picture.
Voyager and Galileo images have been adjusted to provide comparable color balances similar to Voyager color. In the Galileo image the Surt and Aten regions appear much more similar to the Voyager 1 pre-eruption images than to the Voyager 2 images. The Surt and Aten plume deposits had spectral properties similar to the plume deposits of Pele. Pele's deposits have not faded, suggesting that Pele had remained intermittently active whereas Surt and Aten are only rarely active.
