Geology. Kure Atoll emerged between 6 and 25 million years ago, and probably rose to an elevation of over 12,000 feet. Most of the Leewards, including Kure, have been eroded flat by the sea and wind, but a few tough volcanic cores endure. There are over 18 islets, shoals, and half submerged reefs in the chain, with a total area of 3400 acres. Additional seamounts extend another 500 miles northwest of Kure Atoll. This undersea chain not claimed by any country.
