SUNDA STRAIT is the channel separating Sumatra from Java, and uniting the Indian Ocean with the Java Sea. It is 15 miles broad between the southmost point of Sumatra and the town of Anjer in Java. Bight in the middle is the low-lying well-wooded island of Dwars in den Weg, otherwise Middle Island or Sungian. In 1883 Sunda Strait was the scene of the most terrific results of the eruption of Krakatoa, a volcano on the west side of the strait. The greater part of the island of Krakatoa was destroyed and two new islands, Steers Island and Calmeyer Island, were thrown up.
