The paper is dedicated to the modeling of tectonic movements based on GNSS coordinate time series, which were analyzed using the Kalman filter. The research area includes the territory of Japan, which is one of the most seismically active regions on Earth. The devastating Tohoku earthquake of 2011 was the result of subduction between the Pacific and North American plates. Different offsets were observed by analyzing the time series of GNSS coordinates. The intensity of the offset caused by the Tohoku earthquake is proportional to the distance of the observed station from the epicentre of the earthquake. The horizontal and vertical movements of Honshu Island are not homogeneous, which results from the fact that the GNSS stations are located on different tectonic plates.
