The secular variantion of longitudes and plate tectonic motion
Summary According to the plate tectonic theory of Le Pichon [1968] we summarized the absolute values of the angular rate of rotation of the Eurasia and America plates determined by astronomical latitude observations. The authors then tried to use the data of longitude observation so far available to emphasize the existence of similar crust movements. The analysis of longitude data has shown the minor homogeneity of these astronomical observations especially as far as the observations obtained by means of PZT are concerned. By using particularly accurate observational data [Torao & Okasahi, 1965, 1969] the data of longitude variations confirm the existence of movements in the earth’s crust, exactly equal to those deduced by the analysis of latitude observations and in agreement with the results of geophysical measurements.
