Both the 1969 calibration test and Cannikin itself attracted protest . Because of the 1964 Alaska earthquake , the plans raised concerns that tests might trigger earthquakes and cause a tsunami . A 1969 demonstration of 7,000 people blocked a major U.S.-Canada border crossing in British Columbia , carrying signs reading " Do n't Make A Wave . It 's Your Fault If Our Fault Goes " . Further demonstrations occurred at Canada – US border crossings in Ontario and Quebec . The Canadian Do n't Make a Wave Committee founded that year , in Vancouver , attempted to halt further nuclear testing on the Aleutian islands chain that swings across the Bering Sea from North America almost to the Russian coast . With the intention of sailing to Amchitka to protest the 1971 test , the committee chartered a ship it renamed '' Greenpeace '' . The ship was turned back by the U.S. Coast Guard . However , under this name , the organization created for the protest continued to exist as the campaigning environmental organization Greenpeace
