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...
