Earth Dynamics Study



The 56 investigators in NASA's Crustal Dynamics Project met in September at the Goddard Space Flight Center to review the project, which will study the earth's tectonic plate movements, crustal deformation, and rotational dynamics. European investigators convened October 30. Using precise geodetic data obtained with such space techniques as laser ranging and radio interferometry, investigators will study regional crustal deformation in California, Alaska, and other regions of high earthquake activity; the current-day relative motion between the earth's major tectonic plates; the internal stability of the North American and Pacific plates; and variations in the Earth's rotation rate and position of its polar axis. The project will extend through 1986.
