INVESTIGATION ON RECENT CRUSTAL MOVEMENTS BY MICRO-TRIANGULATION NETWORKS

Abstract

The horizontal component of recent crustal movements (surface movements) of tectonic origin is known very slightly in the territory of Hungary because of the low velocity of these deformations and the insufficient accuracy of earlier triangulations. Within the research work of the Geodetic Institute, Technical University of Budapest authors intend to carry out investigations of slow horizontal deformations by periodically re- observed micro-triangulation nets, settled along tectonic faults. Localization of the fault sec· tions was accomplished by interpretation of aerialphotos and space-images. The sketch of the first micro-net built in the vicinity of the village S6skut (Transdanubia) is to be seen in the figure.
