This Envisat radar image features six of Hawaii's eight major volcanic islands. Visible from right to left are the Big Island of Hawaii, Kahoolawe, Maui, Lanai, Molokai and Oahu. In addition to two other major islands, there are also 124 islets. This image was created by combining three Envisat ASAR acquisitions (27 March 2006, 16 April 2007 and 21 January 2008) taken over the same area. The colours in the image result from variations in the surface that occurred between acquisitions.
