A study is carried out for the three component seismograms of the explosion earthquake associated with the first break which took place at 0225 hours. The seismograms which are corrected for mechanical distortions of recording are available for the spectral analyses by means of Maximum Entropy Method and the results of the analyses are compared with those of the 1973 explosion earthquakes. As to the spectral analyses on the initial 5-sec part of the 1982 explosion earthquake, it is concluded that a longer period predominates in the U-D and N-S components compared to those of 1973 in spite of its small seismic magnitude. The results may reflect the difference of mechanisms between the 1973 and 1982 explosive eruptions. Taking into account the results of field observations carried out by SHIMOZURU et al. or ARAMAKI and HAYAKAWA, no molten magma occurred in the 1982 eruption. As to the spectral structure based on the running power spectra by using Maximum Entropy Method, both the 1973 and 1982 explosion earthquakes roughly have similar spectral structure. This is probably because the spectral structure only reflects the geological structure in the volcanic body.", "subitem_description_type": "Abstract"}, {"subitem_description":
