It is prohibited for residents to carry out activities within a radius of three kilometers around the peak of Merapi.
REPUBLIKA.CO.ID, YOGYAKARTA – Head of the Geological Disaster Technology Research and Development Agency (BPPTKG) Yogyakarta Hanik Humaida said the current level of Merapi activity on the mountain was still warning status despite the discovery of new lava domes . Nevertheless, a radius of three kilometers from the summit of Mount Merapi is not allowed for the activities of the residents.
"Radius 3 km from the top of Mount Merapi is not allowed for the activities of the residents Residents living in the disastrous areas Sick to raise awareness," Hanik said during a press conference at BPPTKG Yogyakarta, Saturday (8/18).
Hanik revealed the reason why the status of Mount Merapi had not been increased because the seismic fluctuations were still in the range above normal conditions. And also, this has not shown any significant importance, despite an increase in seismicity since July 18, 2018 and followed by a major storm on August 11, 2018.
"We say that some of the seismicity is indeed high, but it has no show significant influence. "This means increasing the status, we see the development of its sensitivity, for example due to its size (the size of the lava dome), then through the earthquake and then through the growth of the lavava itself,"
Up to now, he continued, the growth of the new lava dome has not been significant either: the dome has a length of about 55 meters, a width of 25 meters and a height of 5 meters. from the surface of the lava dome that was formed in 2010.
It will continue to follow the development of new lava mills that are formed, because perhaps one day the activity of Mount Merapi will increase. "[19659008] " We tried to calculate which growth it was. It was about 1000 cubic meters per day, so it is still very small when we start on 11 August. We see growth, as later there are still earthquakes that exist, which means they will grow. We continue to follow, "he said.
He also called on the community not to worry about the rise of the new lava dome. "So there is nothing to worry about, so if God wants it, we will continue to follow its development," he said.
