Volcanoes of Java, Indonesia7.6S 110.7E
Java (below), the world’s 13th largest island at approximately 139,000 km2, lies between Sumatra to the west and Bali (lower right) to the east. Borneo (above) lies to the north and Christmas Island to the south.
Here, rivermouths along the southern coast of Borneo spill dark brown sediments into the Java Sea. Sediments are also present along the northern coast of Java, although they are lighter in color.
Java is almost entirely of volcanic origin; it contains no fewer than thirty-eight mountains forming an east-west spine which have at one time or another been active volcanoes. Many of this volcanoes are visible here, their peaks ringed by clouds.
The highest volcano in Java is Mount Semeru (3,676 m), the third peak from the right. The most active volcano in Java and also in Indonesia is Mount Merapi (2,968 m), visible in the center of Java in the full image.
Further mountains and highlands help to split the interior into a series of relatively isolated regions suitable for wet-rice cultivation; the rice lands of Java are among the richest in the world.
