This picture was taken from the Space Shuttle using an instrument (called a SIR) that detects electromagnetic radiation in the radar region of the spectrum. The different colors were created by combining information contained in three channels that are sensitive to different wavelengths. North is toward the upper left hand corner of the picture. You can just see the town of Hilo at the very top of the image in the middle. Near the center of the image a large ovate crater can be seen that has a smaller circular crater nested within it. The larger crater is the summit crater, or caldera, of Kilauea volcano and is referred to as Kilauea crater. The smaller caldera within Kilauea crater is called Halemaumau.
