The dark-colored forested area with scattered clouds on the rounded peninsula left of the sharp-tipped Tua Peninsula forming the SE tip of Sumatra is Rajabasa volcano. The NW tip of Java (right) lies across the Sunda Strait in this NASA Space Shuttle image with north to the upper left. The low, conical volcano has a well-preserved 500 x 700 m summit crater with a swampy floor. The age of its most recent eruptions is not known, although fumarolic activity occurs on the foot and flanks of the volcano.
