INDONESIA - Tectonic earthquake in Dompu, West Nusa Tenggara, on Monday morning thought to trigger the volcanic activity of Mount Rinjani. And Mount Barujari condition is not stable yet still be affected by tectonic earthquakes. Causing, scheduled flights from several countries to the island of Bali is delayed
"We suspect that the increased activity (Gunung Rinjani) at this time, is the influence of the quake," said Head of Sub Monitoring Volcanoes Eastern Conference Center for Volcanology and Geological Hazard Mitigation (PVMBG), Devi Kamil Syahbana to Kompas.com, Monday (1 / 8/2016).
Why Mount Tambora and Sangeangapi does not react, whereas, Rinjani which is far from the location of the earthquake, just the opposite?
"In seismology the volcano, it is understood that the volcanic system that is unstable will be more susceptible triggered by the tectonic earthquake. Rinjani now has not really reached equilibrium. The proof is still no smoke is kept out, because of an earthquake," said Devi.
She said the post-eruption of Rinjani in the last quarter of 2015 the activity of small eruptions still occurs occasionally. According to him, it was due to the eruption of Rinjani have long character and the post-eruptive peak itself takes the time to return to equilibrium.
"We are still analyzing whether this improvement of its ongoing (followed by a significant eruption) or transient (temporary, will decline again, as the activity is only triggered by the earthquake)," She explained.
Head of Data Information and Public Relations of National Disaster Management Agency, Sutupo Purwo Nugroho in a press release received Kompas.com say an earthquake in Dompu cause pressure on the stomach, causing the eruption of Mount Rinjani.
As is known, the earthquake shook Dompu, West Nusa Tenggara at 06:40 pm. The quake had a magnitude of M 5.7. Currently, the volcanic activity of Mount Rinjani child led to the closure of Lombok International Airport.
Twitter account the Ministry of Transportation on Monday afternoon, said that the closure of the airport was carried out starting today at 16:55 pm until Tuesday (08.02.2016) at 10:00 pm
"Closing BIL extended until 10:00 hours on 2 August 2016 as the majority of volcanic dust has begun in the area of the airport," said a statement from the Meteorology, Climatology and Geophysics Agency said Monday.
Mount Rinjani or Gunung 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 (Indonesian: Nusa Tenggara Barat, NTB). It rises to 3,726 meters (12,224 ft), making it the second highest volcano in Indonesia.
On the top of the volcano is a 6-by-8.5-kilometre (3.7 by 5.3 mi) caldera, which is filled partially by the crater lake known as Segara Anak or Anak Laut (Child of the Sea) due to the blue color of water lake as Laut (Sea).
This lake is approximately 2,000 metres (6,600 ft) above sea level and estimated to be about 200 metres (660 ft) deep;the caldera also contains hot springs. Sasak tribe and Hindu people assume the lake and the mount are sacred and some religious activities are occasionally done in the two areas. On 31 October 2015, Mount Rinjani started erupting again.
Thus the news of Indonesia with the title Mount Rinjani is active, allegedly due to tectonic earthquakes in Dompu. Quoted from sains.kompas.com
