Shaded relief bathymetry of the Eastern Lau Spreading Center (ELSC) with the locations of the Kilo Moana (-2620 m depth), Tow Cam (-2700 m) and ABE (-2140 m) vent fields indicated with white dots. Dramatic changes in the morphology of the ELSC are evident in this image as the spreading center transitions from a flat deep axial valley, to a well-defined axial valley, to a axial ridge. View is to the north, and vertical exaggeration is 2x. Image made using GeoMapApp.

Shaded relief bathymetry of the Overlapping Spreading Center (OSC) at 22°S along the Valu Fa Ridge (VFR). The locations of the Tui Malila (-1870 m depth), Mariner (-1910 m) and Vai Lili (-1720 m) vent fields are indicated with white dots. View is to the north, and vertical exaggeration is 2x.

Perspective view of the overlapping spreading center discontinuity at 9°03'N along the East Pacific Rise. View is looking north along the ridge axis. Image shows the v-shaped zone of disturbed seafloor left by the southward migration of this discontinuity over the past several million years. Former overlap basins and curved ridges are present on on the west flank of the ridge axis whereas a wide swath of deeper bathymetry and oblique trending faults are present on the east flank. Image made using GeoMapApp.

Perspective view of the axis of the East Pacific Rise from 9°45'N to 9°58'N looking to the north with a close up of the region where the 1991 and 2006 volcanic eruptions were focussed. Image on left is created from bathymetry data from White et al., G-Cubed 2006 (30 m grid interval). Close up image on right is created from ultra high resolution bathymetry data gridded at ~5 meters collected with the Autonomous Underwater Vehicle ABE (Fornari et al., 2004).
