  • Description

    The most powerful underground explosion in world history caused by man set off by U.S. scientists, Nevada, October 30.

    The atomic device, known as "Blanca" was fired in a cavern 850 feet below ground at the end of a 3,000-foot tunnel. It dislodged millions of tons of rock and dust, as the scientists raced a deadline to end the series.

    The device was said to be equal to about 20,000 tons of TNT.

    The blast was felt as a rumbling earthquake to observes about four and a half miles from the firing point. A huge, dirty cloud of dust rose an instant after the blast and towered 2,000 feet in the air.

    As the tests were nearing an end, protests were being made in the U.S. over the amount of radioactivity being caused. The Mayor of Los Angeles telephoned the Atomic Energy Commission asking for an immediate stop to the tests.

    Reassuring statements were made by officials, but it was being claimed that the radiation in the air over Southern California had reached a level 20 per cent. above the accepted safe maximum.
