The Marcoo nuclear test with a yield of 1.5 kt was conducted in Maralinga, Australia on October 4, 1956. The first operational British nuclear weapon, code-named Blue Danube, was exploded on the surface. It produced a 50 meter wide crater and 12 meter deep. In 1967 this crater was used as a burial pit for radioactive soil scraped from the contaminated area.
