Recent Activity

Rinjani erupted 3 times on may 22, 2010 with activity continued till early may 23. consistent with the volcano’s official watching agency, ash from Mount Barujari was rumored as rising up to 2 metric linear unit into the atmosphere and broken crops. The volcano failed to threaten villagers at that point. volcanic rock flowed into the volcanic crater lake, pushing its temperature up from twenty one to thirty five °C (70 to ninety five °F), whereas smoke unfold 12 kilometres (7.5 mi).

In Gregorian calendar month 2010 observers at the Gunung Rinjani post set 1.25 km (4,100 ft) northeast of G. Rinjani saw one whitish-colored plume that rose a hundred metres (328 ft) from the volcano. Dense whitish plumes (and probably brown) rose five hundred to 900 m (1,600–3,000 ft) in March 2010 on twenty six occasions and as high as 1,500 m (4,900 ft) in Apr 2010 on 41 occasions. Plumes seen on one and a couple of may 2010 were “chocolate” in color and rose a most height of one,600 metres (5,200 ft). From Gregorian calendar month 2010 through Apr 2010 seismicity shrivelled, though the utmost amplitude of earthquakes redoubled. CVGHM (Center of vulcanology and geologic Hazard Mitigation) conjointly noted that ash eruptions and ejected incandescent material fell inside Rinjani volcanic crater, however some ash was blown out of the volcanic crater.

The activity in early 2010 centred concerning Gunung Barujari, a post-caldera cone that lies inside the Rinjani’s volcanic crater lake of Segara Anak. The Volcanological Survey of Dutch East Indies rumored on 1 may 2010, that a column of smoke was discovered rising from G. Rinjani “issuing eruptions 1300-1600 metres tall with thick brown color and powerful pressure”. Their report Evaluasi Kegiatan G. Rinjani of 4 may also declared that on one may 2010 at 10:00 four events of Explosive Earthquake were recorded with a most amplitude of 6–53 millimeter and one hundred ten seconds long earthquake, earthquake tremor events with a most amplitude of one millimeter and fifty five second long length, fifteen native Tectonic earthquake events and 2 events of tectonic earthquake.

The Volcanic Explosivity Index (VEI) Alert Level was raised to two (on a scale of 1-4) on 2 may 2010. Level 1 is “Normal” ANd Level 2 is “Advisory” with an Aviation Alert color of Yellow-Advisory. supported analysis of satellite imagination, the Darwin VAAC (Volcanic Ash informatory Center) rumored that on five may a attainable ash plume from Rinjani rose to an altitude of 5.5 kilometres (3.4 mi) a.s.l. and drifted 150 kilometres (93 mi) nw. The plume wasn’t seen in imagination concerning six hours later. CVGHM (Center of vulcanology and geologic Hazard Mitigation) suggested the VAAC that intermittent activity might manufacture ash plumes to 1.5 km (4,900 ft) on top of the volcanic crater.

On twenty seven Apr 2009 Gunung Barujari became active, with activity continued through to may 2009. The mountain was closed at that point because the eruptions intense with plumes of smoke and ash as high as eight,000 m (26,000 ft). A Volcanic Explosivity Index (VEI):2 rating was issued for the activity between 2 may 2009 and 20 December 2009. The activity throughout this era was delineate as having the characteristics of central vent eruption, flank (excentric) vent, explosive eruption and volcanic rock flow(s).

On 31 Oct 2015, Mount Rinjani started erupting once more.
