Estimate of the rate of vertical displacements of the earth's surface and changes in the density of the crust in the south-west of the Baikal rift zone and the Altai mountains according to gravimetric monitoring
In this paper, based on the results repeated measurements of variations of gravity in seismically active areas of the Baikal rift zone and the Altai Mountains assessments have been the possible rate of vertical displacement h the earth's surface and changes in the density of the crust Δ<i>ρ</i>. It is shown that measurements of h can reach values of h = 10 cm per year, and of Δ<i>ρ</i> = 8∙10<sup>-5</sup> g/cm<sup>3</sup> per year and they are associated mainly with the time of near earthquakes.
