Mount Rinjani or Gunung Rinjani is an active volcano in Indonesia on the island of Lombok. It rises to 3,726 m (12,224 ft), making it the second highest volcano in Indonesia. The first historical eruption occurred in September of 1847. The most recent eruption of Mount Rinjani was on 1 October 2004. The volcano and spectacular Segara Anak crater lake, are protected by a national park established in 1997. The 6 km by 8.5 km oval-shaped caldera is filled partially by a lake known as Segara Anak (approximately 2000m above sea level and estimated at being between 200m and 300m deep); the caldera also contains hot springs. The eruptions of 1994, 1995, and 1996 have formed a small cone, Gunung Baru (or Mountain New - approximately 2300m above sea level) in the center of the caldera and lava flows from these eruptions have entered the lake. The highlands are forest clad and mostly underdeveloped. The lowlands are highly cultivated. Rice, soybeans, coffee, tobacco, cotton, cinnamon, and vanilla are the major crops grown in the fertile soils of the island. Tourism is also increasingly popular with trekkers able to visit the rim, make their way into the caldera or even to make the more arduous climb to the highest point, fatalities, however, are not uncommon.

Erupted History
The June 1994 eruption. At 02:00 pm, on June 3rd, 1994, Barujari come began erupting by sending an ash plume 500 m high. On June 8th, press report described emission of "smoldering lava" and "thick smoke", as well as ashfallin nearby villages from an ash cloud rising 1,500 m above the summit. Between 3rd and 10th of June, up to 172 explosions could be heard each day from the Sembalun Lawang volcano observatory (15 km NE). During this period, seismic data indicated a dramatic increase in the number of explosions per day, from 68 to 18,720. Eruptions were continuous at least through 19th of June, with maximum ash plume heights of 2,000 m on 9th to 11th.

The ash plume generally drifted SE, depositing up to 30 mm of ash on the island. Strombolian eruptions ejected pyroclastic material > 2m in size as high as 600 m above the vent; this material fell in a restricted proximal area around the cone and in the lake. Lava flows began on 8th of June and partially covered previous lava flows from Rombongan (in 1944) and Barujari (in 1966).

A series of aircraft warnings based on pilot reports and weather satellite images indicated much larger plumes than suggested by the ground observations. First an eruption at about 12:00 on June 7th produced a long plume that caused a large number of aviation warnings. The plume, located on satellite imagery, extended 120 km S of Rinjani and was beginning to disperse by 15:30. A pilot report at 16:45 indicated a "smoke" plume to 13,500 m altitude moving ESE, but by 23:45 the plume was in distinguish- able on satellite imagery. The imagery showed a plume around 06:33 on the 8th of June, which extended at least 83 km SE of the volcano. Aircraft were advised to avoid this area to an altitude of 10,500 masl.
