From Wikipedia, the free encyclopedia

Former mid-ocean ridge

ThePacific-Kula Ridge is a formermid-ocean ridge that existed between thePacific andKula plates in thePacific Ocean during thePaleogene period. Its appearance was in an east–west direction and theHawaiian-Emperor seamount chain had its attribution with the ridge.^[1] The Pacific-Kula Ridge lay south of theHawaii hotspot around 80 million years ago, moving northward relative to thehotspot.^[2]
