| 内容記述 | Seismic observation was made during the period of August 22 and September 30, 1968 at Merapi Volcano, Central Java, Indonesia. The monitor seismographs were set up at the southern foot and northern flank with the use of smoked paper recording. A data recorder with magnetic tape recording was used as mobile seismic observation. The observation period was characterized by the minimum number of occurrences of lava avalanches, however, seismic activity showed a relatively high level. Most of the volcanic earthquakes indicated typical B-type earthquakes. Tape recorded seismograms obtained just beneath the lava dome showed high frequency oscillation which seems to be the oscillation of a part of the lava dome associated with gas emission. Ground vibration associated with the lava avalanche was observed. Amplitude of earthquakes was abnormally large at Plawangan where the seismic waves of the period 0.4 sec. appear to be selectively amplified. Type of earthquakes observed at Selokopoduwur, just beneath the lava dome, was classified into four according to the vibration period and duration time. High frequency vibration was not observed at Babadan and at Plawangen. Period increase of B-type earthquake with distance was found to be similar to that observed during the development of the lava dome of Showa Shinzan. During the observation, at least ten earthquakes were observed of which epicenters were located near Jogjakarta.|1968年8月22日-9月30日の期間,インドネシア,中部ジャワにあるメラピ火山において地質観測を行った.モニター地震計は煤書き水平動3成分をメラピ火山南麓のプラワンガンとカリウランに置き,カリウランで連続観測を行った.また,9月7日より,メラピ北麓のセロ観測所に煤書き2成分記録計を設置し,水平動地震計を2台,北側山腹に設置した.モニター観測の結果の主要なものは次の通りである. | |||||
