Background

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 EPR 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 AD, and older flows were dated by similar techniques to the 17th and 19th centuries.

Southern EPR-Segment I Photos

After the large bubble explosions, the effusion rate decreases and the lava flow starts slowly to weaken. At the summit strong strombolian activity continues. The vent of the lava flow can be seen from a depression just beneath the southern rim of the main crater (same spot where the 17 Oct explosion occurred). (Photo: Tom Pfeiffer)
