| The Mendana Fracture Zone is a major intra-oceanic feature on the Nazca Plate off Peru. During the Seaperc cruise of R/V Jean charcot in 1986, Seabeam bathymetric data, single channel seismic records, geomagnetic and gravity measurements and heat flow data were obtained over this area. In this paper, we show that the Mendana Fracture Zone is actively opening perpendicular to its trend, resulting in the formation of new oceanic crust since about 3.5 Ma. This new rift is propagating westward along the fracture zone at a velocity of about 17 cm/yr with respect to the trench). The origin of the Mendana spreading centre would be the extensional stress acting parallel to the Peru Trench in this area. |

| 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. |

| The Krakatau project has been launched as a regional study along the Indonesian island arc aiming at understanding the response of an island arc and of its fore-arc to an increased obliquity in the convergence along its subducting border. Along the Sunda island arc, convergence varies from near-to-normal along Java to increasingly oblique along Sumatra, and to near-to-tangent along the Andaman-Nicobar ridge. As a result of this increased obliquity, it has been assumed that the fore-arc region has been mobilized, as a whole as a series of segmented units with a resulting strike-slip motion parallel to the island-arc. |
