Potential to Reappear, Still a Merapi Lava Drop
Jurnal Portal. Jakarta, the Center for Investigation and Development of Geological Disaster Technology (BPPTKG) Yogyakarta stated that Mount Merapi launched an incandescent lava of 300 meters to the upper reaches of Gendol River on Sunday (12/16) night at 19.00 WIB. The incandescent lava drop is still in low intensity.
BPPTKG stated that lava avalanches from Merapi still have the potential to reappear. The head of the Yogyakarta BPPTKG Hanik Humaida in Yogyakarta, said that the collision will continue to emerge as long as there is still the most active growth of lava domes in Indonesia.
"As long as the lava dome is still growing, the collision will still occur," Hanik said on Monday (17/12) quoted by Antara.
Despite the lava avalanches, he requested that the people around the slopes of Mount Merapi, especially those living in Disaster-Prone Areas (KRB) III remain calm and active as usual. The community was also asked to continue to keep abreast of information from BPPTKG.
Based on the Merapi Activity Report, the December 7-13 observation period released by BPPTKG stated that lava domes were still stable with a low growth rate. The volume of lava domes as of December 13, 2018 was 350,000 cubic meters with an average growth rate of 2,200 cubic meters per day.
Furthermore, Merapi seismic activity was recorded 28 times for earthquake gusts (DG), four times shallow volcanic earthquakes (VTB), 9 times as many earthquake episodes (MP), 264 earthquake repairs (RF), 35 times low frequency earthquakes (LF) and 12 tectonic earthquakes (TT).
The intensity of the low frequency seismicity during that period was higher than the previous week.
From the data on the volcanic activity of Merapi, BPPTKG still maintains the status of Mount Merapi at level II or is alert.
The climbing activity of Mount Merapi is temporarily not recommended by BPPTKG, except for the purposes of investigation and research related to disaster mitigation efforts.
