| Many scientists have participated at these Kaiko cruises. Three legs have been studied. The observations show that the trenches around Japan exhibit a whole range of possible subduction processes. It has been demonstrated that the subduction could fairly "swallow" as sharp-pointed fishbones as volcanoes as Fuji Yama or as big lumps as the palau Kyushu volcanic arc. The subduction then changes into collision and these surveys provide the first indications about the way. The transition from the Nankai trench to the Izu collision takes place. Such transition is accompanied by an oceanic lithosphere overthrust. Last, it appears that scars exhibited by the oceanic lithosphere in the form of fossil rift valleys and faults are reactivated upon the bending of the... |

| Active deformation of the sea-floor of the Hellenic trench has been observed using the Cyana SP-3000 submersible. The strain pattern observed on a scale of a few kilometers is similar to the one deduced from an analysis of Seabeam morphological maps on a scale of tens of kilometers. The overall strain pattern is compatible with subduction of the Mediterranean sea-floor toward the northeast. It is characterized by underthrusting in the Western Ionian branch and left-lateral strike-slip faulting in the Eastern Strabo branch. |
