Results of the evaluation of visual and instrumental observation data Mount Rinjani eruption 2015, West Nusa Tenggara until October 25, 2015 is considering the explosive eruption that generates a small scale eruption ash column reached a height of 200 m from the summit Baru jari at 10:04 pm.
On 31 October at 067.50 pm the observed eruption of Mount Baru jari smoke reaches 600 meters above the summit of Mount Barujari the altitude of 3,000 meters.
While on November 1, 2015, at 5:52 pm, the smoke is 3,900 meters high above sea level or 1500 meters above the summit of Mount Barujari.
Recent photo is taken Rinjani eruption Barujari Emergency Response team in Plawangan on 3 November 2015 at 6:59 pm.
While the National Agency for Disaster Management (BNPB) said that Mountain Barujari eruption back. The distribution of ashes toward Southwestern is up to the Northwest from the eruption center at a speed of 10 knots, the surface layer up to an altitude of 14,000 feet. On the morning of the eruption of the sea surface reaching 3,800 meters above sea level or 1,500 meters from the summit of Mount Barujari.
In the event of this nature, National Agency for Disaster Management specify the name of the mountain at this time because of the eruption of Mount Rinjani is appropriate nomenclature than 127 volcanoes in Indonesia.
Mt Rinjani has a height of 3,726 meters above sea level, is located at 08 ° 25 ‘south latitude and 116 ° 28’ East Longitude, precisely in the District Aikmel, East Lombok, Nusa Tenggara Barat (NTB). Other names are Rinjani caldera, which is a crater with water, known as Segara Anak Lake.
Quoted from the site National Agency for Disaster Management morphology or main forms of Actual Rinjani is the morphology of the caldera and volcanic cone. Ellipse-shaped caldera is morphology, with a slope of 60-80 degrees.
There are two cones in the eastern part of the lake is the new Mount Barujari has height of 2,376 meters above sea level and Gunung Mas or Mount delegation, height 2,110 meters above sea level.
Essentially rock is lava and pyroclastic fallout. Morphology volcanic cones occupy the inner walls of the caldera and the cliffs of the caldera.
Slope ranges between 30-70 degrees, with a radial flow pattern of the river, while essentially a fall-pyroclastic rocks.
While the morphology of high hills and low ridge-corrugated morphology respectively located in the eastern, western and parts of the slopes of mountain eruption complex peaks and slopes down Rinjani complex. Each of the two final morphology characterized by having a steep slope with a slope angle of 30-80 degrees and the angle of slope of less than 30 degrees.
Product caldera or crater is the result of paroxysmal eruption (the eruption sweeping secrete large material) Mount Rinjani Old destroyed the summit of Old Mount Rinjani. The eruption produced a caldera ellip and has shaped with a diameter of 2.4 x 4.8 km. That just short information About Rinjani eruption in 2015
