The aim is to capture and monitor continuing developments to Merapi, which began unleashing torrents of hot gas, ash and molten rock more than two weeks ago after years of dormancy. The death toll from a series of eruptions has risen to 206.
Volcanologists have said that the installations would be of vital importance, considering that visual monitoring of eruptions is difficult under current conditions, with heavy rainfall in recent days and thick fog enveloping the mountain’s peak.
Hot ash was flowing at a slower rate down from the volcano on Friday, but experts continue to warn residents to stay away in case of another eruption.
Raden Sukhyar, head of geology at the Ministry of Energy and Mineral Resources, said on Friday that the volcano appears to be entering a resting phase as the intensity of eruptions declines.
“Merapi calmed down after it erupted on October 26. However, the volcano surprised us with its worst eruption in the last century on November 5, after more than a week of rest,” Sukhyar said.
The monitoring equipment to be installed on Merapi has already proven its success in Japan, said Masato Iguchi, a Japanese volcanologist. He said the equipment, worth 5 million yen ($60,900), had been placed at the foot of mountains in Japan and had facilitated more accurate monitoring of volcanic activity.
“The equipment is to be installed outside the danger zone, but within 20 kilometers from Merapi’s crater. We will place it in the Prambanan subdistrict of Sleman, about five kilometers from Prambanan Temple,” Iguchi said.
Kyoto University sent a total of four volcanologists to assist Indonesian volcanologists and to conduct research on the phases of Merapi’s recent eruptions.
The infrasonic microphones will also help to detect the release of lava, Iguchi said. However, Subandrio, head of the Volcano Investigation and Technology Development Institution (BPPTK), said the high-tech microphones can only detect air pressure changes that occur in cases of eruption, but not lava as such. “We will put up three lava sensor geophones to detect vibrations caused by lava flows,” he said.
These tools will be installed in several of the areas that were most severely damaged by recent flows of lava.
Surono, head of the Volcanology and Geological Disaster Mitigation Agency (PVMBG), said that the same infrasonic microphones had already been installed on Mount Krakatau in the Sunda Strait and Mount Semeru in East Java.
“The microphones provide accurate data that can be used for statistical analysis, in addition to the data obtained from seismometers and visual observation, but they cannot predict when a volcano will stop erupting,” he said.
The National Disaster Management Agency (BNPB) said on Friday that Merapi’s death toll had gone up from 194 to 206, as people who died from respiratory problems, heart attacks and other illnesses related to the eruptions had been included in the count.
kita dikejutkan dengan bencana ledakan letusan merapi.. daripada video tersebut, bencana merapi telah menyebabkan kematian lebih 100 orang penduduk.
bencana tersebut menyebabkan penduduk kehilangan sumber makanan. para sukarelawan sanggup membantu mereka.
pelajar Malaysia yang berada di sana dibenarkan pulang.. sama-sama kita doakan bencana merapi akan berkurangan..amin.

Yogyakarta. Working with Kyoto University of Japan, Indonesia is scheduled to install three infrasonic microphones to capture sound waves of eruptions at Mount Merapi even as volcanic activity shows signs of decline.
