Gilbert and Ellice Islands colony caused the Polynesians of the Ellice Islands to vote for separation from the Micronesians of the Gilbert Islands (later Kiribati). The following year, the Ellice Islands became the separate British colony of Tuvalu. In 1947 Tarawa, in the Gilbert Islands, was made the administrative capital. This development included establishing The King George V Secondary School for boys and the Elaine Bernacchi Secondary School for girls. A Colony Conference was organised at Marakei in 1956, which was attended by officials and representatives from each island in the Gilbert and Ellice Islands Colony, conferences were held every two years until 1962.
Geology of the Pacific Ocean existed. In a remote region of the central Pacific Ocean, at the southeastern section of the Gilbert Islands, a major swarm of intraplate earthquakes occurred between December 1981 and March 1983, with no prior seismicity having been reported in this region previously. Another swarm was detected on the Queen Charlotte Islands fracture zone in August–September 1967. The Pacific Ocean contains several long seamount chains, formed by hotspot volcanism. These include the Hawaiian–Emperor seamount chain, the Tasmantid Seamount Chain, the Lord Howe Seamount Chain and the Louisville Ridge.
