NASA announced it would deploy seven laser satellite-tracking systems in the United States and the Pacific Ocean as part of a global network to extend conventional measurements of strain in the Earth's crust and to seek the causes of earthquakes. The lasers, to be in full operation by October, would work with microwave devices using signals from satellites and radio stars to measure crustal movements and the buildup of strain.
Laser systems using corner-cube reflectors put on the Moon by the United States and the Soviet Union were operating in Texas, Australia, and West Germany; satellite-laser systems were operating in France, Spain, Germany, Greece, Egypt, England, and the Netherlands. The Smithsonian Astrophysical Observatory had laser systems in Peru, Brazil, and eastern Australia. NASA had joined NOAA, the U.S. Geological Survey, NSF, and the Defense Mapping Agency in a program using space technology to reduce earthquake hazards and possibly to develop a capability of predicting them.
