The rock-deformation data series collected by extensometers provide an opportunity for studying various changes in the geological, rock-physical environment, caused by earthquakes (e.g.,displacement, deformation of rock mass). Hereby further information can be achieved about the nature of these effects, complementing the analysis of seismograms (as e.g. the frequency range embraced by extensometers can record changes with much higher time of periods). In order to investigate the appearance of effects of earthquakes in extensometric data, authors chose a registratum which was collected in the Matyashegy Gravity and Geodynamical Observatory in Budapest in the time of a significant M7.2 earthquake occurred in Turkey, and started its spectral analysis. Results of the examinations were compared to the spectrum of records of a typical, undisturbed lapse of time, as well as to the spectrum calculated from seismogram of Kövesligethy Radó Seismological Observatory in Budapest, nearby the gravity observatory.
