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.
This photo from the space Shuttle shows the islands of Java, Bali, Lombok,
and Sumbawa (from left to right). The view is to the north across the
volcanic arc. Space Shuttle photo STS068-0160-0053.
The volcanoes on these islands are: Java (Raung, Ijen, and Baluran), Bali
(Bratan, Batur, and Agung), Lombok (Rinjani), and Sumbawa (Tambora).
