• Mount Agung Update: Flame of Fire Visible at the peak of Mount Agung, But Status Stay Alert? This is BNPB Explanation

    AMLAPURA – Mount Agung erupted again on Saturday (25/11). After spraying volcanic ash puffs up to a height of 1500 meters at 17:30 pm, at the peak of the mountain and then visible flame or embers start at 23:00 pm.

    “There was a flame or a fire on the summit of Mount Agung on 25/11/2017 at 23:00 pm Black gray smoke is still coming out from the crater,” said Head of BNPB Information and Public Relations Data, Sutopo Purwo Nugroho, last night.

    Added, currently the team of Volcanology Center for Geological Hazard Mitigation (PVMBG) is still doing an analysis related to the appearance of the red flame. “The PVMBG team is still continuously analyzing and monitoring intensively Gunung Agung’s current activities,” he explained.

    Yesterday afternoon, Mount Agung, located in Rendang Village, Karangasem, was again erupted. The thickness of the thick, medium-pressure black smoke reaches 1,500 meters above the top of the crater.

    The height of volcanic ash eruption in this second eruption is twice higher than the first eruption on Tuesday (21/11) at 17:15 pm. At that time Mount Agung eject volcanic ash with a medium pressure with a height of 700 meters.

    “It’s just an eruption again.This is taller, more or less 1,500 meters.This is an eruption containing ash material, but we still have to analyze the composition of the ashes,” said Head PVMBG, Kasbani, confirmed yesterday afternoon.

    There was a thick ash puff with medium pressure, ash column as high as 1,500 meters from a crater that was bent toward the southwest. The phreatic eruption is continuous.

    At around 21.30 pm, thin ash falls in some villages around Mount Agung, particularly in the southwest sector, such as Besakih Village, hamlets in the upper part of Pempatan Village, and Temukus Village. Volcanic ash is clearly visible on the car windows or attached to the vehicle.

    Until 23:00 pm, smoke and volcanic ash are still monitored out of the crater. The analysis results of the BMKG Himawari Satellite shows that the spread of volcanic ash leads to the southwest in the direction of the wind.

    Three Seismic Stations

    Based on information Magma VAR PVMBG, the second eruption occurred at around 17:30 Wita by removing the volcanic material in between gray and black ash with a thick intensity.

    PVMBG can visually observe the bursts of ash from three seismic stations in Dukuh Village, Culik Village, and Batulompeh to the southwest-southwest with moderate pressure. The direction of the volcanic ash blast corresponds to the direction of the wind that blows weakly towards the west.

    Even this eruption can be witnessed directly by local residents. The reason, d uring the second eruption yesterday, the peak of Mount Agung looks more clear. In contrast to a few days earlier that was covered in fog.

    The eruption this time is the second in a week, after the first eruption occurred on Tuesday (21/11). But this type of eruption can not be ascertained whether including freaktif eruption or freatomagmatik eruption. PVMBG is still doing research.

    Phreatic eruption in general is the opening eruption of the magmatic eruption (main eruption). Phreatic eruption occurs due to high pressure water vapor. Water vapor is formed along with underground water heating or rainwater that seeps into the soil inside the crater, and then direct contact with magma.

    Phreatic eruption accompanied by smoke, ash, and material in the crater. High freactic eruptions vary, can reach 3000 meters, depending on the strength of water vapor. The impact of this eruption is rain of ash, sand or gravel around the mountain.

    While the freatomagmatic eruption usually occurs after a phreatic eruption. The eruption is driven by a direct interaction between magma and water. These eruptive smoke clouds also contain ash materials with larger and concentrated sulfur content than phreatic eruptions.

    The eruption is also characterized by rock / lava incandescent, heavy ash rains and the possibility of sounds heard. Even this eruption will be followed by a hot cloud.

    In general phreatic and freatomagmatic eruptions are the process of dismantling the crater pipe is clogged, before the magma out to the surface or the occurrence of magmatic eruption (main eruption).

    The ash sample will then be analyzed for the ash particle content. Is there any new magma material (juvenile) or not. If there is no juvenile, then includes a phreatic eruption. Meanwhile, if it contains juvenile it is a freatomagmatic eruption.

    Status Standby

    Until last night, PVMBG still continues to analyze the second eruption that occurred yesterday. There is no increase in seismic and volcanic activity after eruptions with this 1500 meter high ash.

    Status of Mount Agung until last night remain Standby (Level III). There is no increase in volcanic status. PVMBG continues to monitor and analyze volcanic activity.

    The recommendation also remains that to avoid any activity within a 6 km radius plus a sectoral extension of 7.5 km to the North-Northeast, Southeast and South-Southwest.

    “The people keep calm and follow PVMBG’s recommendation on Level III (Siaga) status, that is to avoid any activity within 6 km radius plus sectoral extension as far as 7.5 km,” said Head of Mitigation Division of East Volcano Monitoring PVMBG, Devy Kamil Syahbana, yesterday.

    Mentioned, the Hazard Danger Zone is dynamic and can be changed at any time following the latest or most recent observations of Mount Agung.

    Affected areas include Banjar Belong Hamlet, Pucang, and Pengalusan (Desa Ban); Dusun Banjar Badeg Kelodan, Badeg Tengah, Badegdukuh, Telunbuana, Pura, Lebih, and Sogra (Sebudi Village); Dusun Banjar Kesimpar, Kidulingkreteg, Putung, Temukus, Besakih, and Jugul (Besakih Village); Dusun Banjar Bukitpaon and Tanaharon (Desa Buana Giri); Dusun Banjar Yehkori, Untalan, Galih and Pesagi (Village of Jungutan); and some areas of Dukuh Village.
