"After eruption 26 October, has formed the crater 200 meters at the top of the mountain, but because of the eruption in early November was estimated to be 10 times larger than the Oct. 26, the crater formed is also expected larger until doubled," said Head of the Ministry of Geology Energy and Mineral Resources (EMR) R Sukhyar, in the office of Investigation and Technology Development Center (BPPTK) Yogyakarta, Saturday night (7 / 11).
However, further Sukhyar, it can not be sure exactly wide crater and morphology of the summit of Mount Merapi as the peak of the mountain is still shrouded in fog so that impede visual monitoring. He asked the public to keep alert because of Merapi activity is still high based on instrumental observation data using a seismograph in BPPTK.
"Fluctuations of Mount Merapi is still high enough so that the alert status of Merapi remains and the area affected is also still the same ie a radius of 20 kilometers," explained Sukhyar.
Based on field observation, pyroclastic deposits can reach a distance of 12 km in the Kali Boyong with a thickness of up to 10 meters. Therefore, further Sukhyar, the threat of Mount Merapi is not only clouds but also flood lava hot especially when exposed to a fairly heavy rain on the slopes. "People are still advised to stay away from flood plains because the wall can be eroded river banks or otherwise have an interest, not for too long on the move on the bridge," he warned.
A number of river channel needs to be avoided is Woro Kali, Kali Gendol, Kali Kuning, Boyong Kali, Kali Bedog, Krasak, Bebeng Kali, Kali Sat, Kali Lamat, Krasak, Kali Senowo, Trising Kali, and Kali Apu.
Currently, more Sukhyar, BPPTK still try to add the monitoring tools in three point three seismometers replace damaged due to hit the eruption of Mount Merapi. However, he said, observation and analytical skills development volcanic activity is not interrupted even when the appliance is damaged because there remained a seismometer in Plawangan.
