Hello travelers, how was your trip? today I will deliver an interesting place of interest that you must to visit when you have a trip in Indonesia. Mount Rinjani is the second highest volcano in Indonesia at 3,726 m. It dominates the landscape of the relatively small island of Lombok. Within its huge 50 km² caldera sits the crater lake Segara Anak (Child of the Sea). Eruptions within the caldera have formed a new small cone called appropriately enough, Gunung Baru (New Mountain). Segara Anak has a natural hot spring. 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.
Well, this Mount also be a favorite trekking and hiking place for many travelers from around the world. In 2008, the Indonesian government proposed to UNESCO that Mount Rinjani be one of the world’s official geoparks. 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. Well Guys that the history about the second highest mount in Indonesia, this mount also has many place of interest that could you visit along your trip in Lombok island. Mount Rinjani is also great place for you to showing your trekking and hiking skill with many variations of route Guys.
