Mount Rinjani is an active volcano in Indonesia on the island of Lombok. Administratively the mountain is in the Regency of North Lombok, West Nusa Tenggara. It rises to 3,726 metres, making it the second highest volcano in Indonesia.
The park covers an area of 41,330 ha on the northern part of Lombok. Named after Indonesia’s second highest volcanic peak outside of West Papua, the peak of Gunung Rinjani (3,726m) dominates the landscape. Within the crater is the spectacular Segara Anak lake and the still-active volcano Gunung Baru (2,363m). It is surrounded by a further 66,000 ha of Protection Forest and covers the four administrative district of West, East, north and Central Lombok. The park ecosystem is in the transitional zone between Asia and Australia (Wallace zone). Average rainfall is about 3,000 mm annually.
Gunung Rinjani is rich in a variety of flora, fauna and vegetation types. On the south western side of the mountain is the most eastern extent of primary rain forest in Nusa Tenggara. This gives way to monsoon forest and drier climate in the east, and savannah in the north east. Notable flora includes the everlasting
- Edelweiss flower (Anopheles viscid),
- Tiger orchid (Vanda sp.),
- Alang-alang grass (Imperata cylindrical),
- Cemara trees (Casuarinas trifoliate and Casuarinas occidental).
Mt. Rinjani, one of the over 40 National Parks throughout Indonesia, was established in 1997. It is valued and protected for its spiritual as well as natural values, and is worshiper by thousands of Balinese as well as Sasak pilgrims. Hot springs near the crater lake are sought after for their healing powers. Over 20 villages surround Rinjani and there are many routes up the mountain, but the main access is from Senaru in the north and Sembalun Lawang to the east. The challenging three-day Rinjani Trek route from Senaru to the crater rim (Plawangan), down to the stunning crater lake then on to Sembalun, is considered one of the best treks in South East Asia. Those heading for the summit usually prefer to start in Sembalun
Rinjani Mountain Fauna
Lombok is East of the Wallace Line and some bird species with Australasian affinities are therefore apparent. These include
- Cockatoos and
- Green hanging parrots,
- in addition to species whose heartland is to the West including tits, weavers and tailor-birds. Bird life can be difficult to observe here due to the density of the forest, though if you have patience and are practiced at mimicry many species can be tempted out from cover – if you have the time to spare and the forbearance of your trekking partners.
History of Gunung Baru Jari (New Mountain)
The oldest recorded historical eruption was in 1847. Previous to that this was a very remote region indeed, hence the lack of records.
There was a spate of activity from 1994 to 1995 which resulted in the further growth of the crater cone Gunung Baru, since renamed Gunung Barujari (Finger Mountain).
On 27 April 2009 Gunung Barujari became active again with that activity continuing through to May 2009. The summit ascent routes were closed at that time as the eruptions intensified with plumes of smoke and ash as high as 8,000 m. A Volcanic Explosivity Index (VEI):2 rating was issued for the activity between May and December 2009. The ascent routes re-opened on September 14th 2009 but hiking routes down into the crater lake were still deemed unsafe and remained closed.
In February 2010 observers at the Gunung Rinjani Observation Post detected a smoke plume that rose 100 m from the volcano. The activity in early 2010 is centred about Gunung Barujari. On May 1st 2010 a column of smoke was again observed rising from Rinjani issuing eruptions 1,300-1,600 metres tall with thick brown color and strong pressure. On May 5th 2010 a possible ash plume rose to an altitude of 5.5 km (18,000 ft) and drifted 150 km NW. Accordingly the Center of Volcanology and Geological Hazard Mitigation advised that intermittent activity could produce ash plumes to 1,500 m (5,000 ft) above the caldera. In light of this The Volcanic Explosivity Index Alert Level was raised to 2 with a recommendation that there be no activity within a radius of 4 km from the eruption at Gunung Barujari.
Rinjani Mountain Lenght
The mountain and its satellites form the Mount Rinjani National Park (Taman Nasional Gunung Rinjani) – officially 41,000 hectares within the park boundaries and a further 66,000 hectares of protected forest outside.
In 2008, the Indonesian government proposed to UNESCO that Mount Rinjani be one of the world’s official geoparks. If this was approved by UNESCO, Mount Rinjani would become the first such geological park in Indonesia.
