. * Further tests did occur in the Pacific, but they were in the vicinity of Johnston Island and Christmas Island, so far to the east that there was no effect upon Eniwetok Atoll. These tests followed the 1 September 1961 announcement by the U.S.S.R. of its intention to resume nuclear testing. The U.S.S.R. tests occurred within days of this announcement. Many months later the United States started testing under a series called Operation Dominic, but, as just stated, not at Eniwetok Atoll. This test series was completed by the end of 1962 and was followed by the Limited Test Ban Treaty, which was signed in September 1963. This Treaty prohibited all nuclear tests except those conducted underground. Although underground tests have beeh con- ducted in the continental United States and at Amchitka in Alaska, none have been conducted at Eniwetok Atoll. 4g In these test series, a total of 43 nuclear detonations or attempts ui nuclear déLonations have been made at Eniwetok Atoll.
