VOLCANIC COMPOSITION 
In Lombok, Rinjani volcano lies approximately 300 km north of the Sunda Trench (also known as Java trench ) and is situated about 170 km above the active north dipping Benioff zone. Based on the composition of andesites which have very low Ni concentrations and low Mg/Mg+Fe It is suggested that the Rinjani suite is of mantle origin, but that all the andesites and dacites as well as many of the basalts have probably been modified by fractional crystallization processes.[25] It is concluded that the Rinjani calc-alkaline suite, which in many respects is typical of many suites erupted by circum-pacific volcanoes, probably originated by partial melting of the peridotite mantle-wedge overlying the active Benioff Zone beneath Lombok Island.
The Pleistocene-Recent calcalkaline suite from the active volcano, Rinjani is composed of a diverse range of lavas. These include: ankaramite, high-Al basalt, andesite, high-K andesite and dacite. Sr-isotopic and geochemical constraints suggest that this suite was derived from the sub-arc mantle. Geochemical models suggest that fractional crystallization is an important process in the suite’s differentiation, although the series: ankaramite-high-Al basalt-andesite-dacite does not represent a continuously evolving spectrum of liquids.Click to add text, images, and other content
RECENT ACTIVITY OF MOUNT RINJANI
Rinjani erupted three times on May 22rd 2010 with activity continuing until early on May 23th. According to the volcano’s official monitoring agency, ash from Mount Barujari has been reported as rising up to two km into the atmosphere and has damaged crops. The volcano is not currently threatening villagers. Lava flowed into the caldera lake, pushing its temperature up from 21°C to 35°C, while smoke spread 12 km.
In February 2010 observers at the Gunung Rinjani Observation Post located 12.5 km (4000 feet) NE of Rinjani saw one whitish-colored plume that rose 100 metres (328 ft) from the volcano. Dense whitish plumes (and possibly brown) rose 500 metres (1,640 ft) – 900 metres (2,953 ft) in March 2010 on 26 occasions and as high as 1,500 metres (4,921 ft) in April 2010 on 41 occasions. Plumes seen on 1 and 2 May 2010 were “chocolate” in color and rose a maximum height of 1,600 metres (5,249 ft). From February 2010 through April 2010 seismicity decreased, although the maximum amplitude of earthquakes increased. CVGHM (Center of Volcanology and Geological Hazard Mitigation)[31] also noted that ash eruptions and ejected incandescent material fell within Rinjani caldera, but some ash was blown out of the caldera.
The activity in early 2010 centred about Gunung Barujari a post-caldera cone that lies within the Rinjani’s caldera lake of Segara Anak. The Volcanological Survey of Indonesia reported on 1 May 2010, that a column of smoke was observed rising from G. Rinjani “issuing eruptions 1300-1600 metres tall with thick brown color and strong pressure”. Their report Evaluasi Kegiatan G. Rinjani of 4 May also stated that on 1 May 2010 at 10:00 four events of Explosve Earthquake were recorded with a maximum amplitude of 6-53 mm and 110 seconds long earthquake, earthquake tremor events with a maximum amplitude of 1 mm and 55 second long duration, 15 Local Tectonic earthquake events and two events of tectonic earthquake. The Volcanic Explosivity Index (VEI) Alert Level was raised to 2 (on a scale of 1-4) on 2 May 2010.[33] Level 1 is “Normal” and Level 2 is “Advisory” with an Aviation Alert color of Yellow-Advisory.[34]Based on analysis of satellite imagery, the Darwin VAAC (Volcanic Ash Advisory Center) reported that on 5 May a possible ash plume from Rinjani rose to an altitude of 5.5 km (18,000 ft) a.s.l. and drifted 150 km NW. The plume was not seen in imagery about six hours later. CVGHM (Center of Volcanology and Geological Hazard Mitigation) advised the VAAC that intermittent activity could produce ash plumes to 1.5 km (5,000 ft) above the caldera.
On 27 April 2009 Gunung Barujari became active with activity continuing through to May 2009. The mountain was closed at that time as the eruptions intensified with plumes of smoke and ash as high as 8,000 m (26,250 ft). A Volcanic Explosivity Index (VEI):2 rating was issued for the activity between 2 May 2009 and 20 December 2009. The activity during this period was described as having the characteristics:of central vent eruption, flank (excentric) vent, explosive eruption and lava flow(s).
GEOLOGIC SUMMARY
On the basis of Plate Tectonics Theory, Rinjani is one of the series of volcanoes built in the Lesser Sunda Islands due to the subduction of Indo-Australian oceanic crust beneath the Lesser Sunda Islands, and it is interpreted that the sources of melted magma is at about 165–200 km depth.
The geology and tectonic setting of Lombok (and nearby Sumbawa) are described as being in the central portion of the Sunda Arc. The oldest exposed rocks are Miocene, suggesting that subduction and volcanism began considerably later than in Java and Sumatra to the west, where there are abundant volcanic and intrusive rocks of Late Mesozoic age. The islands are located on the eastern edge of the Sunda shelf, in a zone where crustal thickness is apparently rapidly diminishing, from west to east.
The seismic velocity structure of the crust in this region is transitional between typical oceanic and continental profiles and the Mohorovi?i? discontinuity (Moho) appears to lie at about 20 km These factors tend to suggest that there has been limited opportunity for crustal contamination of magmas erupted on the islands of Lombok and Sumbawa. In addition, these islands lie to the west of those parts of the eastern-most Sunda and west Banda arcs where collision with the Australian plate is apparently progressing.
The volcano of Rinjani is be located between 165 and 190 km above the Benioff Zone. There is a marked offset in the line of active volcanoes between the most easterly Sumbawa Volcano (Sangeang Api) and the line of active volcano in the Flores. This suggests that a major transcurrent fault cut across the arc between Sumbawa Island Flores. This is considered to be a feature representing a major tectonic discontinuity between the east and west Sunda Arcs (the Sumba Fracture Further. A marked absence of shallow and intermediate earthquake
activity in the region to the south of Lombok and Sumbawa is a feature interpreted to represent a marked break in the Sunda Arc Zone. Faulting and folding caused strong deformation in the eastern part of Lombok Basin and is characterized by block faulting, shale diapirs and mud volcano.
GEOGRAPHIC SUMMARY
Lombok is one of the Lesser Sunda Islands, a small archipelago which, from west to east, consists of Bali, Lombok, Sumbawa, Flores, Sumba and the Timor islands; all are located at the edge of the Australian continental shelf. Volcanoes in the area are formed due to the action of oceanic crusts and the movement of the shelf itself. Rinjani is one of at least 129 active volcanoes in Indonesia, four of which belong to the volcanoes of the Sunda Arc trench system forming part of the Pacific Ring of Fire – a section of fault lines stretching from the Western Hemisphere through Japan and South East Asia. The islands of Lombok and Sumbawa lie in the central portion of the Sunda Arc. The Sunda Arc is home to some of the world’s most dangerous and explosive volcanoes. The eruption of nearby Mount Tambora on Sumbawa is known for the most violent eruption in recorded history on 15 April 1815, with a scale 7the VEI.
Rinjani volcano on the island of Lombok rises to 3,726 metres (12,224 ft), second in height among Indonesian volcanoes only to Sumatra’s Kerinci volcano. Rinjani has a steep-sided conical profile when viewed from the east, but the western side of the compound volcano is truncated by the 6 x 8.5 km, oval-shaped Segara Anak caldera. The western half of the caldera contains a 230 metre-deep lake whose crescentic form results from growth of the post-caldera cone Barujari at the eastern end of the caldera.
