...suggestion to ban the big, controllable tests. In addition, he suggested that all powers "voluntarily ban, for 'four or five years,'" the low-yield underground tests that could not be monitored. Meanwhile, the Soviets would support the U.S. call for an all-out drive to develop seismic methods to detect such elusive blasts. For all its pitfalls, the bid seemed to contain two Soviet concessions: that small tests would not have to be banned permanently, and an admission that the control system needs to be improved...
...this report, U.S. and British scientists led by the U.S.'s Dr. James Fisk and Britain's Sir William Penney set down their revised findings (TIME, Jan. 12, 1959 et seq.) that known techniques of seismic detection of underground tests were completely unreliable. The U.S. had gone into the Geneva talks 14 months before on the basis of a single seismic detection of a single underground test explosion-the Rainier shot in September 1957-but had pulled up short after the Hardtack shots in Nevada in October 1958 could not be distinguished from small earthquakes. The Russian scientists...
...prospects for agreement have been injured by the recent unwillingness on the part of the politically guided Soviet experts to give serious consideration to the effectiveness of seismic techniques for the detection of underground nuclear explosions," it read. "Indeed, the atmosphere of the talks has been clouded by the intemperate and technically unsupportable Soviet annex to the report...
...cave 3,000 ft. down and 950 ft. in diameter-an excavating job equal to removing a mass of material equal in volume to the concrete in 42 Grand Coulee dams-it would muffle a 300-kiloton bomb so much that the explosion "might be made to appear seismically like one kiloton. This could not be distinguished by the Geneva seismic network from the thousands of natural earthquakes of this magnitude occurring every year." Similarly muffled, an explosion of 100 kilotons might not be detected...
...Weather Bureau last week. Back from 15 months with the Russians at Mirny on the Indian Ocean coast of Antarctica, Rubin revealed that a Russian party trekked about 1,500 miles inland to the "pole of inaccessibility," setting off dynamite charges in the ice to make seismic soundings every 30-50 miles. Echoes showed continuous land instead of a complex of islands or submerged mountains. The Russians say the land ranges from 2,500 to 12,000 ft. above sea level, with ice up to 3,000 ft. thick covering the high points...
