On may additionally fifth 2010 a likely ash plume rose to an altitude of five.5 km (18,000 ft) and drifted a hundred and fifty km NW. hence the center of Volcanology and Geological hazard Mitigation counseled that intermittent pastime may want to produce ash plumes to 1,500 m (5,000 ft) above the caldera. In light of this The Volcanic Explosivity Index Alert stage turned into raised to two with a advice that there be no interest within a radius of 4 km from the eruption at Gunung Barujari.
Rinjani erupted three in addition times on 23 may also 2010 with activity persevering with until 24 may also 2010. in line with the volcano’s authentic tracking business enterprise, ash from Mount Barujari turned into said as rising up to two km into the ecosystem and broken plants. Lava flowed into the caldera lake, pushing its temperature up from 21°C to 35°C, whilst smoke spread 12 km. The volcano did not at once threaten villagers during any of the eruptive activity in early 2010 however get right of entry to to some sections of the Mountain changed into officially closed or restrained at some instances.
The lower and mid tiers of the mountain are quite heavily forested. Above the tree line though the slopes are barren and rugged scree slopes and volcanic rock. The perspectives of the crater lake are quite breath-taking from the caldera rim, as is the dawn. From absolutely the height you may see Bali to the west and Sumbawa to the east.

Casuarina woodland (cemara) takes over higher up and eventually these provide manner to an alpine plants above the treeline.
Lombok is East of the Wallace Line and some chook species with Australasian affinities are therefore apparent. those include honeyeaters, cockatoos and inexperienced striking parrots, further to species whose heartland is to the West which includes tits, weavers and tailor-birds. chook life can be difficult to observe here due to the density of the woodland, even though when you have persistence and are practised at mimicry many species can be tempted out from cowl – when you have the time to spare and the forebearance of your Rinjani Trekking companions.
