The first time nuclear testing was done in the Pacific was in 1946. Tests were conducted at the Marshall Islands, Bikini Atoll and a few other "nondescript" sites. Testing continued by the US in the Pacific up until 1962.
France also conducted its own tests in French Polynesia, between 1966 and 1996.
Nuclear weapons were used twice in combat against the Japanese Empire in 1945. In order to decisively end the Pacific War Hiroshima and Nagasaki became the only cities (in so far) to witness a nuclear holocaust. Many nuclear tests have been conducted since, with hydrogen and neutron types also detonated. The last suspected nuclear tests were by North Korea in February 2013.

There were several locations: New Mexico, Pacific, Nevada, Space, etc. The general idea was a remote location to reduce hazards to civilians. In several tests it didn't work out that way.
The French tested their nuclear weapons in the Sahara desert (before Algeria's independence) and on the Pacific atoll of Mururoa.
