| Реферат: | eng: Measurements of non-tidal variations of gravity which were obtained from 1992 to 2014 at Talaya seismic station (located in the south-western part of Baikal region), are interpreted together with GPS observation data which were obtained from 2000 to 2014 at the same station. An absolute gravimeter was used for gravity observation. The linear component of gravity variations corresponds to changes in the elevation of the site. The correlation coefficient is close to the normal value of the vertical gradient of gravity. At this site, coseismic gravity variations at the time of Kultuk earthquake (27 August 2008, Mw = 6.5) were caused by a combined effect of the change of the site's elevation and the deformation of the crust. Our estimations of coseismic effects are consistent with results obtained by modeling based on the available seismic data. Post-seismic variations are discussed too. © State Research Center of the Russian Federation Concern CSRI Elektropribor, JSC, 2016. |
