为了调查在西南日本引起大地震的菲律宾板块的插入情况,日本和联邦德国的研究人员将从1984年9月14日开始,在九州以南海域联合进行大规模的海底地震观测。日德联合观测海底地震,这是第一次。目前还没有关于这个海域地下深部板块插入情况的资料,因此,人们期待着继前些日子以日本海沟为中心的日法联合调查之后的新的成果。日德的这次调查计 In order to investigate the insertion of the Philippine Plate that caused the major earthquake in southwestern Japan, researchers from Japan and the Federal Republic of Germany will jointly conduct a large-scale seabed seismic observation in the waters south of Kyushu beginning September 14, 1984.
