The Yogyakarta Geological Disaster Technology Research and Development Center (BPPTKG) recorded that Mount Merapi’s eruption material had vomited up to 111 times in the period 19-25 November 2021. The furthest slide of material was up to 2 kilometers. Berita Terkini
On November 20, 2021, one hot cloud fell to the southwest with a sliding distance of 1,800 meters. Then 110 times lava falls to the southwest with a maximum sliding distance of 2,000 meters,” said Head of BPPTKG, Hanik Humaida when contacted, Friday, November 26 2021. Berita Politik
Apart from the eruption, he said, the morphological changes of Mount Merapi did not appear significant. According to him, the volume of the southwest lava dome is 1,610,000 cubic meters and the central dome is 2,927,000 cubic meters.
hot cloud avalanches (AP), Deep Volcanic earthquakes (VTA) once, Shallow Volcanic earthquakes (VTB) twice, Multiple Phase earthquakes (MP) 70 times, Avalanche earthquakes (RF) 938 times, Blowing earthquakes (DG) 89 times, and Tectonic earthquake (TT) once. Berita Hari ini
Hanik said the monitoring data showed that the volcanic activity of Mount Merapi was still high enough that it was still on alert status. The danger is in the form of lava avalanches and hot clouds in the southeast-southwest sector as far as a maximum of 3 kilometers to the Woro river and as far as 5 kilometers to the Gendol, Kuning, Boyong, Bedog, Krasak, Bebeng, and Putih rivers.
Meanwhile, the ejection of volcanic material in the event of an explosive eruption can reach a radius of 3 kilometers from the summit. We continue to urge the surrounding district governments to continue to take mitigation efforts,” he said. Finance Solutions
