Southern EPR at 18.5°S (Segment I)
About Southern EPR at 18.5°S (Segment I)
The narrow axial crest of Segment I of the Southern East Pacific Rise in some places is less than 50 m wide. An axial dome is located along the southern part of the segment. The largest lava flow field in this segment is the Animal Farm flow, named after a thriving low-temperature hydrothermal site discovered during a submersible expedition in 1993. The Animal Farm lava flow was dated by magnetic paleointensity measurements at about 1880-1950 CE, and older flows were dated by similar techniques to the 17th and 19th centuries.
