Lombok Island

On the island of Lombok is located the large, stratovolcano of Gunung Rinjani that is part of Segara Anak Caldera. Rinjani stretches to about 3 miles (5 km) in diameter. This caldera has been active as recently as 1966. On May 21st, 1966 lava and a strong sulfur odor were detected at the Gunung Baru cone. The previous activity was in November of 1915 when smoke was reportedly emitted from Rinjani (U.S. Geological Survey Bulletin 1855, Vol 1, p327). Both images of this volcano were taken from the U.S. Space Shuttle using color infrared (CIR) film in May 1992. The most recent eruption of Rinjani was in June-July, 1994.
