The important problems of the GPS measurements are the searches of the earthquake precursors and study of irreversible and varying displacement of the Earth crust, due to the strongest earthquakes. With development of GPS systems and improvement of satellite technologies of measurements and methods of processing there was possible to in detail register the processes occurring during activization of seismicity. GPS measurement with the large frequency of registration of satellite signals are the powerful tool of study longperiodical waves at the strongest earthquakes. There are considered the examples of registration of the irreversible and coseismical horizontal displacements and deformations of the Earth crust surface arising during the tectonical processes, accompanied the strong earthquakes (Izmit by 1999, Alaska 2002, Sumatra 2004 etc.).
