Differences of latitudes and of mean latitudes of stations located along a common meridian were studied in order to find influences of local geophysical phenomena on their variations. Some correlation of variations of the mean latitude of Belgrade with the occurrence of earthquakes in the vicinity can be noticed as well as instabilities of the mean latitude of stations located near sea coasts. Some attempts at measurements of variations of the meridian component of the vertical and a discussion of spectral analysis of latitudes and of mean latitudes of considered stations are presented.
