WebEast 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. WebThe East Pacific Rise near Easter Island is the fastest spreading mid-ocean ridge, with a spreading rate of over 15 cm/yr. The Pacific Plate moves generally towards the northwest at between 7 and 11 cm/yr while the Juan De Fuca Plate has an east-northeasterly movement of some 4 cm/yr. Most subduction zones around the rim of the Pacific are ...
