Data of continuous extensometer observations at two stations located within the Russian Plate of the East European Platform are analyzed. The comparative evaluation of recent strain rates was performed with the use of a map of geomorphological and geotectonic regionalization, a map of recent vertical movements, and GPS data. Linear strain rates estimated from extensometer observations in both areas studied are of the same order of magnitude and amount to a few units of 1 x 10(-7) per year. The prevailing extension of rocks is oriented N-S; the net E-W strain over the period under consideration is zero. The inferred estimates agree, in both value and direction, with geomorphological and neotectonic observations, as well as with geodetic measurements and GPS data. Activation periods of the deformation process were observed at both the stations, which may be evidence of their regional nature. Anomalies in earth tide waves are attributed to local tectonic features.
