Tuvalu at the Pacific Games similarly rotated on a four-year basis in the intervening years between the main games. A combined Gilbert and Ellice Islands team participated at the 1963, 1966, and 1971 South Pacific Games. An athlete from Tuvalu (then Ellice Islands), namely Nelu Arenga, is at least documented for 1971. Athletes from Tuvalu attended the 2003 South Pacific Games for the first time. Logona Esau was the first athlete from Tuvalu to win a medal at an international competition, when he took bronze at the 2005 South Pacific Mini Games in Koror, Palau. Tuvalu competed at the 2007 Pacific Games in Apia, Samoa.
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.
