The cruise was planned as one of the programs of a joint study by two DELP seafaring research groups, JGDGBAB and JDRGDSOL (refer to authorship footnotes). Preliminary results of studies on the seismic structures, heat flow , and marine geomagnetic measurements are obtained with the aim of clarifying the geometrical and mechanical scheme of the collision and subduction between two oceanic plates, the Philippine Sea Plate subducting underneath the North American Plate (Japan land mass), and collision and distortion among three plates: Pacific Plate, Philippine Sea Plate and North American Plate (Japan land mass). The concept \u0027Japan land mass\u0027does not seem to be equivalent to the plates, but we use this term because it is not unequivocally understood whether the northeastern-eastern part of the Japan land mass, including the Kanto Plain, Tohoku and Hokkaido, belongs to the North American Plate or the Eurasian Plate (eg. Seno, 1985). However, we prefer to assign this part of the Japan land mass to the North American Plate all through this article just for convenience in spite of its ambiguity. The scientific objectives, area surveyed, cruise period, terms of observation, filing of data, and names of participants in this program, and some of the main results and interpretations obtained so far, are presented in Part 1. More details of data acquisition, analysis and interpretation are presented in the later parts. Also described in Part 1 are some new results and findings obtained very recently at the time of this writing and not mentioned in other parts. Data and interpretation obtained by other cruises related to the present program are also referred to in the concluding section of this part.", "subitem_description_type": "Abstract"},
