Field seismic observations by portable broadband seismometers in the Luetzow-Holm Bay region, East Antarctica
Field seismological observations were carried out at five points around the Lutzow-Holm Bay region in East Antarctica to clarify the heterogeneous structure of the crust and the upper mantle during the 37th Japanese Antarctic Research Expedition (JARE-37) and JARE-38 in 1996-97. The seismological re...

Field seismological observations were carried out at five points around the Lutzow-Holm Bay region in East Antarctica to clarify the heterogeneous structure of the crust and the upper mantle during the 37th Japanese Antarctic Research Expedition (JARE-37) and JARE-38 in 1996-97. The seismological recording system is composed of a portable broadband seismometer, a recording unit with MO disk drive and a solar power battery supply. Expect for power supply trouble, the observations went well and waveforms of some teleseismic events were recorded. Based on spectral analysis, the spectrum amplitude of the field observation data is very large at frequency higher than about 0.5Hz. On the other hand, the amplitude is almost the same as that at Syowa Station at frequencies from about 5mHz to 0.5Hz.
