- Аннотация: Based on the data of differential satellite interferometry, the field of displacements of the Earth’s surface in the lineofsight direction is determined for the region of the Altai Earthquake that struck on Sep tember 27, 2003. The displacements are estimated for unforested areas of Chuia and the Kurai depressions, and for a part of their mountainous surroundings. In that part of the region where unwrapping of the data was possible, the amplitude of displacements amounts up to 150 cm for Chuia and 100 cm for the Kurai depres sions. In order to locate the surface of the seismic rupture and to find the field of displacements on this sur face, the method for the combined inversion of the displacements data, provided by satellite interferometry (the present work) and geodesy [Gol’din et al., 2005], is suggested and applied. The admissible range of the parameters of the rupture was specified from the seismology and seismotectonics data. The combined use of geodetic and satellite interferometry data makes the solution of the inverse problem more stable and yields a seismic momentum estimate, which is consistent with the seismological determina tions. We discuss the possible contributions of various postseismic processes; in particular, based on analyzing the energy of the aftershocks, we assess the contribution of the postseismic creep to the displacements, deter mined from the interferometry and geodesy data, for different coseismic and postseismic time intervals.
