LAS VEGAS — A nuclear weapons test detonated beneath the Nevada desert Thursday swayed high-rise buildings here, 100 miles from Ground Zero, and registered 5.6 on seismographs.
The device was detonated 40 miles from Mercury, a tiny town on the Nevada Test Site where Soviet nuclear scientists are based while preparing for a joint U.S.-Soviet test next month.
It was the eighth announced U.S. nuclear weapons test this year at the Nevada Test Site, and the fifth since Soviet scientists arrived in Nevada.
The nuclear weapon, code named "Alamo," was buried 2,000 feet beneath Pahute Mesa, a 5,000-foot-high volcanic plateau in a remote area of the test site. The U.S. and Soviet verification test will also be conducted beneath Pahute Mesa.
