AbstractIt may be argued that a correlation must exist between the tectonics of a region and the fault-planes of the earthquakes of this region. This correlation exists but it is not possible to determine it readily. It is found that one must consider the nodal direction in these earthquakes and it is observed that nodal directions are, in general, normal to the direction of tectonic displacement. Consequently, it is possible to determine the direction of tectonic displacement by a least-squares method. This method has been applied to some Asiatic earthquakes for which numerous observations have been published in the Russian geophysical literature. A remarkable uniformity of tectonic displacement has been found in continental Asia, extending from Sakhalin to the Pamirs and the mountains of Kopet Dagh. This result indicates a large scale uniformity of tectonic forces in the Earth's crust.
