VIVAnews - Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) memperoleh bantuan tiga mikrofon infrasonik untuk membantu proses pemantauan aktivitas Gunung Merapi.
Mikrofon infrasonik akan segera dipasang untuk mempertajam pantauan terhadap aktivitas gunung teraktif di Indonesia itu agar diketahui grafik aktivitas Merapi lebih cepat dan baik.
Alat itu bantuan dari empat ahli vulkanik dari jepang yaitu, Prof Kenji Nogami, Prof Masato Iguchi, Takayuki Kaneko, dan Satoru Ishii.
Mikrofon infrasonik itu telah dipasang di gunung api yang ada di Jepang. Pemasangan mikrofon infrasonik tersebut juga akan dilakukan di Gunung Krakatau dan Semeru. Salah seorang ahli vulkanik dari Jepang, Prof Masato Iguchi mengatakan, proses erupsi Gunung Merapi telah mengundang perhatian peneliti dunia, sehingga dirinya bersama dengan tiga ahli vulkanik datang ke Yogyakarta untuk berusaha ikut memahami fase-fase Merapi. "Alat ini mampu merekam perubahan di puncak merapi dari sistem suara yang dikeluarkan. Sangat membantu ketika puncak Merapi tertutup kabut,” paparnya, Jumat 12 November 2010. Erupsi Merapi pada 2010 mengalami perubahan tipe letusan apabila dibandingkan sebelum 2006. "Kami akan memberikan pendampingan kepada PVMBG dari sisi keilmuan," tuturnya. Sementara itu, Kepala Pusat Vulkanologi dan Mitigasi Bencana Geologi, Surono menjelaskan, dengan alat mikrofon infrasonik itu akan diperoleh grafik data yang lebih akurat. Karena, pengamatan yang dilakukan petugas di lapangan tidak pernah mendengar letusan, tapi hanya mendeteksi getaran. "Alat ini mampu menangkap gelombang tekanan udara yang ditimbulkan letusan Gunung Merapi," katanya. Dengan tambahan alat itu, diharapkan data yang masuk akan mudah dianalisis sebagai data statistik tambahan yang akurat soal aktivitas dan jumlah letusan. "Jadi tidak hanya berdasarkan pengamatan visual dan alat pada seismometer," ujarnya. (art)

BalasHapusVIVAnews - Center for Volcanology and Geological Hazard Mitigation (PVMBG) obtained a three microphone infrasonic assistance to help the process of monitoring the activities of Mount Merapi.
Infrasonic microphones will soon be installed to enhance the monitoring of active volcanic activity in Indonesia was to be known graph Merapi activity faster and better.
Tools that help from four experts from Japanese volcanic namely, Prof. Kenji Nogami, Prof. Masato Iguchi, Takayuki Kaneko and Satoru Ishii.
Infrasonic microphones had been installed at the volcano in Japan. Installation of infrasonic microphones will also be conducted at Mount Krakatoa and Semeru.
One of Japan's volcanic expert, Prof. Masato Iguchi said, the eruption of Mount Merapi has invited the attention of researchers world, so he along with three experts volcanic came to Yogyakarta to try to come to understand the phases of Merapi.
"This tool is able to record changes in the top trim of the sound system is removed. Very helpful when Merapi summit shrouded in fog," he explained, Friday, November 12, 2010.
Merapi eruption in 2010 changed the type of eruption when compared to before 2006. "We will provide assistance to PVMBG of the scientific side," he said.
Meanwhile, the head of Volcanology and Geological Hazard Mitigation, Surono explained, by means of infrasonic microphones that will be obtained more accurate data graph. Because, as observed in the field officers had never heard of the eruption, but only detect vibrations.
"This tool is able to catch the wave of air pressure caused the eruption of Mount Merapi," he said.
With additional equipment, it is expected that incoming data will be easily analyzed as additional statistical data are accurate about the activity and amount of eruption. "So not only based on visual observations and tools on a seismograph," he said. (Art)
