Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Southern EPR-Segment I
"Black smoker" vents (low chlorinity fluids, 374 deg C) were photographed at the "RM28" site at 18 deg 26 min S on Segment I of the Southern East Pacific Rise in November 1994 from the Japanese submersible Shinkai 6500. The narrow axial crest of Segment I of the Southern East Pacific Rise in some places is less than 50 m wide. The largest lava flow field in this EPR segment is the Animal Farm flow, named after a thriving low-temperature hydrothermal site discovered during a submersible expedition in 1993.
