The image is obtained using two shots, one taken before and one taken after the eruption (03/04/2010 and 19/04/2010). In the image, it is possible to distinguish changes in the signal recorded by the radar: these can be identified by the presence of red and green areas.
The new openings in the crater are clearly visible on the right of the image with the bright green edge. The large areas of dark red and green surrounding the crater and extending eastwards can be interpreted as changes caused by the melting ice and deposits of ash expelled by the volcano during the eruption.
The blue zones represent areas where there has not been any change.
Red: 03/04/2010

The false colour image, obtained from a different elaboration of the same data, shows changes in the red and light blue area. On the left of the image are clearly visible traces left by researcher on the surfaces of the glacier.
