The French conducted nuclear testing in the Tuamotu islands, on the atoll of Mururoa. The US conducted nuclear testing on the atoll of Bikini in the Marchall islands.
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.

The Bikini Atoll is an atoll in the Marshall Islands and was the site of many American nuclear tests in the 1940s and 1950s.
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.
No, underground nuclear tests cannot alter the Earth's axial tilt. The axial tilt of Earth is determined by gravitational interactions with other celestial bodies and is not influenced by nuclear tests.
The US tested nuclear devices in the Trinity test site in NM, Bikini atoll in the Marshal islands, Eniwetok atoll in the Marshal islands, underwater offshore Mexico in international waters south of San Diego CA, the Nevada test site north of Las Vegas NV, in space, and for project Plowshare (peaceful uses of nuclear explosives) in about half a dozen other states.The USSR tested nuclear devices at 2 or 3 sites in Siberia and its largest fusion bomb tests were on the arctic island of Novaya Zemlya.The UK tested nuclear devices in Australia.France tested early nuclear devices in the Sahara desert while it still had colonies there, since then I'm not sure.
None.
Following WW2, the Marshal Islands in the pacific (where the test shots were done) became a US protectorate. By international law the US could use them for anything they wanted. Other countries could complain if they didn't like something the US chose to do... but it would take an act of war to force the US to stop testing if they didn't already want to stop. International law already allowed it.The last pacific tests were in 1958.
The 1950s atomic test site in the Pacific is known as the "Bikini Atoll." It was the location of numerous nuclear tests conducted by the United States during the mid-20th century as part of the nuclear arms race. The testing had lasting environmental and health impacts on the local inhabitants and ecosystem.
The first test at Pokhran was in 1974, there were more tests in 1998
