Developments in Geotectonics, 16: Recent Crustal Movements, 1979 covers the proceedings of the IUGG Interdisciplinary Symposium No. 9, ""Recent Crustal Movements"", held in Canberra, A.C.T., Australia on December 13-14, 1979. The book focuses on instruments and methods for the determination of crustal movements; methods of evaluating crustal movements; and interpretation of the crustal structure and crustal movements with the assistance of other geophysical data. The selection first offers information on the design and error characteristics of a fundamental global geodetic network; state and prospects of development of high-precision geodetic methods for studying crustal movements; and interferometric techniques for measuring horizontal earth crustal movements. The text then takes a look at the vertical crustal movements of the Carpatho-Balkan region and height changes and vertical crustal movements in Western German areas. Discussions focus on vertical movements map, instrumental improvements for the observation of vertical crustal movements, and map of height changes and vertical crustal movements. The text ponders on the episodic block motion and convergence along the Calaveras fault in central California and complete determination of local crustal deformation from geodetic observations. The selection is a valuable source of data for geologists and readers interested in crustal movements.
