wtf is this at the bottom of the sea? -- peace :) update - they're man made atolls of some sort. from wiki ; Minamikojima is a completely artificial islet created in shallow water. But also the two original islets appear completely artificial today, with little if any trace of the two natural rocks that still appear on photographs of 1987. In 1925, there were still five above-water rocks, which have eroded since. A report from 1947 mentions five above-water rocks. Three smaller ones were on the west side, nearly impossible to see from seaward because of the breaking waves. The larger rocks on the southwest side and on the northeast side, possibly Kitakojima and Higashikojima, were reported to be 0.6 m (2 ft) and 0.4 m (16 inches) high, respectively. The original rocks appeared barren, obviously without any terrestrial vegetation. The current artificial dry land areas with their concrete surfaces appear unfit to support terrestrial vegetation either. After concrete encasing, each of the islets appears as a circle with a diameter of 60 meters (about 200 ft) on detailed satellite images, which would correspond to a land area - albeit mostly artificial - of 2827 m2 (0.7 acres) per islet, or 8482 m2 (2.1 acres) in total. In addition, there is a platform on stilts in the shallow part of the lagoon 140 meters (460 ft) ENE of the southern islet, built by the Japan Marine Science and Technology Center in 1988, which appears as a rectangle of 100 m by 50 m (330 ft by 165 ft).
