East Pacific Rise

 

a submarine middle range of the Pacific Ocean, which, unlike other midocean ranges, is greatly displaced toward the eastern boundary of the ocean. Length, approximately 8,000 to 9,000 km. Highest point, 539 m above sea level (Easter Island). The depth at the foot of the rise is 3,500 to 4,000 m. In cross section the profile looks like a broad wave with a narrow, raised crest zone.
