Independent state of Samoa

Independent state of Samoa

Fig. 4.22 . The topography of Savai’i (background) and Upolu (foreground), the two large islands of the Independent State of Samoa. The highest volcano rises 1.9 kilometers. The low-lying coastal lands were inundated on 29 September 2009 by a tsunami generated by a major earthquake located about 200 kilometers to the south. Villages located on the coasts are also in danger of flooding by rising seas expected from future global warming. Color-coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations. Bright and dark shades display topographic slope in the northeast-southwest direction. The Shuttle Radar Topography Mission aboard the Space Shuttle Endeavor acquired the elevation data used in this image on 11 February 2000. (Courtesy of NASA/JPL/NGA.)
