COSMO-SkyMed multitemporal image of the Icelandic volcano Eyjafjallajoekull

The image is obtained using two acquisitions, one before and one 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 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 been no change.

• Red: 03/04/2010

• Green: 19/04/2010

• Blue: Coherence
